The information about a printer model's escape sequences and so on are held in the various "filters" which are programs called by `lpd' to drive the printer. `/etc/printcap' simply gives the locations of these filters. For details RTFM(printcap). [Alternatively the net-HOWTO has a summary of some of the more important fields.] One last point - you should always specify `suppress header' `:sh:' unless you have a *text* (not PostScript) printer and want banners. On a text printer they are usually a waste of time and paper. On a PostScript printer they usually stop your printer working. See Also: Burst/banner pages. 3.8 The Syntax of `/etc/printcap' ================================= Ideally RTFM(termcap) (yes, I said *termcap*) but since most people don't have TFM(termcap) here are the essentials. Lines starting with `#' are comments (as you might have guessed). For each printer usable from the `lpr' command on your system there is one logical line in the file. For the sake of readability each logical line may be spread over several physical lines by making the last character on all but the last physical line a backslash. Each logical line has the following format: NAME1|NAME2|NAME3:STRING_CAPABILITY=STRING:\ :NUMERIC_CAPABILITY#NUMBER:BOOLEAN_CAPABILITY: The leading spaces and colon on the second line are for readability only. A printer can have as many names as you like but conventionally the final name is used as a longhand description of the printer. (Still people are free to say `lpr -P "grotty teletype in room 213"' if that's the description you've given.) One of the names of your default printer must be `lp'. The list of capabilities can be as long as needed and the order is not significant. Each "capability" is denoted by a two character code. (The name "capability" comes form the file format's termcap heritage - parameter or attribute would be a more sensible terms.) [Note from Ross Biro: capabilities with 3 character names don't work properly which is why the serial port stuff in the old binaries failed.] Capabilities having string value and have a `=' delimiter between the capability name and the value while those having a numeric value use a `#' (actually they can use either a `#' or an `='). Boolean "capabilities" are true if they appear in the list and false if they do not. Special characters in a string value can be expressed using backslash-escaped sequences as in C; in addition, `\E' stands for ESC. `^' is also a kind of escape character; `^' followed by CHAR stands for the control-equivalent of CHAR. Thus, `^a' stands for the character control-a, just like `\001'. `\' and `^' themselves can be represented as `\\' and `\^' respectively. `\:' for `:' seems to work but the source code contains a warning that it can confuse the parser and `\072' is a better idea. Example: lp|bam|Epson FX-80:lp=/dev/lp1:sd=/usr/spool/lp1:sh:mx#0:\ :df=/usr/local/lib/magic-filter/lp.df:\ :if=/usr/local/lib/magic-filter/lp.if: The printer's name is `lp' (this is the printer that `lpr' uses by default). It's also known as `bam' or `"Epson FX-80"'. The printer is on `/dev/lp1' (aka AT-bus LPT1:). I don't want a burst page. I don't want a file length limit. Files queued by `lpr -d' areem of your `/usr' filesystem filling up as a result of stuff in spool queues. The main configuration file is `/etc/printcap'. Network printing also uses `/etc/hosts.allow' and `/etc/hosts.lpd'. By now everyone should have libraries and binaries that look for config files in `/etc'. If you chose to keep your configs somewhere else (`/conf' or `/usr/etc' for example) then `/etc' must contain a symlink to the real file. If you still have a system which looks for files in `/usr/etc' or `/etc/inet' your system is way out of date and you should upgrade. 3.5 lpd not working =================== If `ps ax' does not reveal a `lpd' then you daemon has died (or was never started) - usually a sign that it couldn't create its lockfile, or was unable to find `/etc/services'. (This will happen if you tried to start it before all your filesystems were mounted). If `lpr' works only for root then you've probably got a permission problem. If you cant even `cat' files to the printer then you may be using the wrong device name for the printer in `/etc/printcap' See Also: Printer device names or you may need to fiddle with `tunelp'. See Also: hardware and drivers. If you get "jobs queued, but cannot start daemon" or "lpc: connect: No such file or directory" while `lpd' is running then you are having trouble with the socket connection to `lpd'. "start" in the context of this error really means "wake". This problem has come and gone thoughout the history of Linux - I don't really understand this but it stems from an erroneous interaction between the networking stuff and "Unix domain" (non-network) sockets. Usually it has only shown up when the network is incorrectly configured. If you're not really on a network it is usually adequate just to have the following somewhere in your startup. ifconfig lo localhost route add localhost You'll also need to have the `/etc/hosts' file. There's no need to run any daemons. There is second and much more understandable way to produce this error - use a mixture of components from different releases of lpd that use different names for the Unix domain socket (new stuff uses `/tmp/.printer', obsolete stuff `/dev/printer'). (For some time SLS was released this way). At the time of writing I am quite unable to reproduce this error - I am using my debugged version of the net-2 lpd compiled with gcc-2.4.5 and libc-4.4.4 on kernel 0.99.14. 3.6 Where Do I Get A Printcap For Printer Model xxxxx? ====================================================== This question is essentially meaningless so please don't ask it on usenet See Also: The Semantics of /etc/printcap. 3.7 The Semantics of `/etc/printcap' ==================================== Given the similarity in appearance and name between `/etc/termcap' and `/etc/printcap' one could be forgiven for assuming that they contain analogous infomation. This is not the case. Whereas `/etc/termcap' contains informations about terminal *types* - (mostlhat you believe that you have specified what you think are the correct flags and baud rate in printcap; check `stty -a < /dev/ttyS2' (or whatever your printer port is). If the settings are not correct, check your flags against your printout from termios.h. If the settings are *way* not correct, you may need a fixed lpd. The patch follows, and you can probably see why it's needed :-) Note: this patch is reversed and has already been applied (uh... unapplied :-) ) to lpd-590p2 so don't apply it if you already have that version or later. (the patch is coming in just a sec) When I was setting mine up, I followed a sequence like this: lprm WHATEVER # (make sure queue is empty and lpd is running) stty CORRECT SETTINGS < /dev/ttyS2 lpr SOMETHING SMALL stty -a < /dev/ttyS2 # (often had to ctrl-c out of this one) twiddle with flags lprm WHATEVER # make sure queue is empty again... Here's the patch (I it's reversed so apply it with `-R' - or, in practice, by hand!): -------------------------------Cut Here------------------------------------- *** lpd-590/lpd/printjob.c Thu Jul 8 20:56:59 1993 --- lpd-590/lpd/printjob.c~ Sat Feb 27 09:07:01 1993 *************** *** 1271,1277 **** } #ifdef LINUX ttybuf.c_cflag &= ~FC; /* not quite right! */ ! ttybuf.c_cflag |= FS; /* not quite right! */ #else ttybuf.sg_flags &= ~FC; ttybuf.sg_flags |= FS; --- 1271,1277 ---- } #ifdef LINUX ttybuf.c_cflag &= ~FC; /* not quite right! */ ! ttybuf.c_cflag |= ~FS; /* not quite right! */ #else ttybuf.sg_flags &= ~FC; ttybuf.sg_flags |= FS; -------------------------------Cut Here------------------------------------- 3.16 Printers that are not simple devices ========================================= [Firstly I'll explain the subject.] The most common example is a printer that is connected via a network in some strange way. For example consider a printer connected to a host with which you can only communicate via E-mail. To use such a printer through `lpr' the `lp' capability of the print queue should be directed to a `/dev/null' type device (e.g. `mknod /dev/null1 c 1 3') but not `/dev/null' itself as `lpd' opens the device exclusively. Each filter must must explicitly uuencode and mail its output. In more complex cases if you already have an `if' or `of' filter for a strangely connected printer then other filters can pass their output to/through this filter to avoid duplication of effort. In this case the `if' filter should usually be called with the `-c' switch to minimise the further manipulations if performs. I've heard someone has had some success trying something like this with Novell NetWare and the free mail transfer agent "Charon". 3.17 Generating burst or banner pages ===================================== For a simple text printer (in particular not PostScript) and a simple text banner simply take `:sh:' out of the printcap record. If you want to prevent the banner comming out in whatever font was last used on the printer then define the `tr' "capability" to be your printer's font reset command. If you want a fancy customised banner (or have a PostScript printer) leave `:sh:' in the printcap and make each of your filters print the banner. All the information to put on the banner is included in the filter's positional parameters. RTFM(printcap) for details. [ If you're using 's magic-filter package then call the code to print the banners from the config script. ] 3.18 Spooling text to a PostScript printer ========================================== You need a filter based on a program that converts ascii to PostScript. The most well known of these is `enscript' but it's also the hardest to find (being non-free). Others include `a2ps', `nenscript', and `mpage'. See Also: Printing text via PostScript. 3.19 Why graphics files are sometines truncated =============================================== This is usually because you've got a limit set on the maximum size file that can sit in the spool queue. Put `mx#0' in your printcap. 3.20 Why `lpr -i' doesn't work ============================== To get `lpr -i' to work you need a filter installed as `if' that implements it. The `-i' switch is simply passed on by `lpd' to the filter. The filter called `lpf' that comes with `lpd' supports this feature but can only be used to print text. If you whant to use this program but still want your filter to do some printer specific initialisation then write script thus: #!/bin/sh # My initialisation stuff goes here exec /usr/lib/lpf $* More reasonably you could have your filter script send the printer left margin sequence. #!/usr/bin/perl # This example is in perl for a change because converting numbers # to characters is tricky in shell script for ($i=0; !($_ = $ARGV[$i]) || !/^-i([0-9])+/; $i++) {} print pack("cAc",27,"l",$1); while () { print; } 3.21 Why `lpr -p' doesn't work? =============================== Because it's broken. `lpd' always thinks that the printer is 0 characters wide regardless of what `/etc/printcap' or the `lpr' arguemnts say. The lpd-FAQ contained a patch but it has now been applied to lpd-590p1 and later. (Appologies to anyone who wanted this patch after the lpd-FAQ merged with printing-how.to. It was dropped in the mistaken belief that a new release of lpd-590 was iminent). One other thing: `lpd' calls `pr' by full pathname so if you keep `pr' somewhere different from `/usr/bin/pr' you will need a symlink. (Where `lpd' expects to find `pr' may vary from version to version). 3.22 `lpc' and `lpq' warning of missing daemons =============================================== One `lpd' process runs all the time and it spawns children to handle each printer as needed. The health of the master daemon is not explicity reported by `lpc' but the absence of errors indicates that it is healthy. See Also: lpd not working. The `lpc stat' command will display the message "no daemon present" for each queue that is not actually printing at the time - this is completely normal. If printing has been disabled or the queue is empty then this is not an error condition. `lpq' is even more alarmist and will say "Warning: no daemon present". If the daemon is absent when the queue has entries and has not been explicitly stopped then this warning probably indicates an error in a filter. Fix the filter then use `lpd up QUEUE-NAME' to restart it. Sometimes when shutting down a printer `lpc' will get confused and try to kill a non existant daemon. This leads to irritating but harmless error messages. In lpd-590p2 these are much rarer. 3.23 Using `lpr' over a network =============================== To print on the printer listed as `foo' in the printcap on machine `bar.baz.net' from the machine `mine.baz.net' you put an entry like this in your `/etc/printcap' (on `mine.baz.net'): foo:lp=:rm=bar.baz.net:rp=foo:sd=/usr/lpd/spool/foo: and, of course, create the spool directory `/usr/lpd/spool/foo'. There's no point specifying filters and the like in `mine.baz.net:/etc/printcap' as it's the ones in `bar.baz.net:/etc/printcap' that will get used. On the machine `bar.baz.foo', you need to put `mine.baz.net' on a line by itself in either `/etc/hosts.equiv' or `/etc/hosts.lpd'; note that putting it in `/etc/hosts.equiv' will allow for unauthenticated logins as well as printing. `/etc/hosts.lpd' is for printing only. The machines listed in `/etc/hosts.*' should be described canonical names or numbers as lpd starts with the IP address and performs a revervse DNS lookup to get the name. If you are not sure of cannonical name you can just list all the names you know for a machine. (If you have `dig' then the command `dig -x A.B.C.D' can be used to get the canonical name of IP address A.B.C.D.) If the printer server is not nunning a BSD style spooler then it should still be possible to get it to work but the authority files may have a different names or formats. For example Chris Nystrom found that he had to create a file on the remote machine called `/usr/spool/lp/admins/lp/Systems' that listed his Linux box's name. We do not know if this is a SYSV thing or something exclusive to dynix/ptx 2.0.3 that he is using on his Sequent. If you can't get remote printing to work thrugh lpd you may be able to simply use remote command exectution like this: rsh bar.baz.net "lp -dlp" < FILE This example would be for a remote system using a SYSV type printing system on host `bar.baz.net'. 3.24 Writing lpd filters ======================== In normal Un*x terminology, filters are just programs (so they must have execute permission) that read a stream from their standard input and write to their standard output. lpd filters are filters in the sense that thay read STDIN and write to STDOUT, but are unusual in that they may assume that their standard input is a random acess file file and may perform lseek() operations on it. All lpd filters have a common command line syntax (or more often simply ignore command line parameters). For details of the command line parameters RTFM(printcap). If you want to write a shell script filter it must have a #!/bin/sh (or perl or csh) header. Here is the generic form of a filter to accept PostScript. #!/bin/sh /PATH.../gs -q -dSAFER -dNOPAUSE -r??? -sDevice=?????? -sOutputFile=- - Place the full pathname of the script as one of the filters (but not `of'!) parameter in the printcap for your printer. I suggest putting such scripts in `/usr/lib/lpd/'. It is also usual to keep filters in the spool directories but this goes against normal practice of keeping programs and data neatly apart. (`-dSAFER' attempts to protect against PostScript interpreter security holes, `-q' and `-dNOPAUSE' make it run nonstop, and Device is the appropriate special file for your printer). Here is an Epson FX-80 dvi filter using ghostscript: #!/bin/sh /usr/TeX/bin/dvips -f | \ /usr/bin/gs -q -dSAFER -sDEVICE=eps9high -r120x216 \ -dNOPAUSE -sOutputFile=- - More tools useful for making filters are described elsewhere in this document. 3.25 Debuging lpd filters ========================= It's easier to debug filters if you test them in an immediate shell before you install them. (If your filter makes use of its command line arguments you'll have to specify them too). `my-new-filter /dev/lp1' A trick most people find useful when testing filters that make use of their command line arguments is to include `echo $* >>/tmp/filter-log' near the top of the script. If the filter works when you test it but still doesn't work when called by `lpd' then you may have forgotten the `#!/bin/sh' header. You may also need to set PATH within the script since the daemon's PATH may not have everything you need. Note also that the filter is run with uid=daemon so any programs it calls sould be world executable. 3.26 Output (`of') filters ========================== Never use these. (Well strictly speaking there are circumstances but you're unlikey to meet them). Recently (early '94) there has been a spate of preople on c.o.l.help advokating the use of output filters. Using `of' filters means that if a printout is queued while another is already printing the 2 will be run together with a form-feed between. Any printer initialisation or file type detection will therfore not be performed for the second file and it will probably be printed incorrectly. There are other more subtle ways in which output filters can do unexpected things. IMHO: If using an output filter is the answer, it was probably a silly question. This is Info file Printing-HOWTO.info, produced by Makeinfo-1.55 from the input file printing.texinfo. A guide to printing and previewing files under the Linux operating system. Copyright (C) 1994 by Grant Taylor and Brian McCauley 3.27 Getting filters for given printers ======================================= From: B.A.McCauley@bham.ac.uk (Brian McCauley) Because writing a filter usually takes about 10 minutes once you've found the right program (`gs', `dvilj' etc.) there's little call for ftp archives of printer filters but we are thinking of creating an extensive example file to go with this document. If you already have a program to print, say, DVI on your printer by some mechanism then making it into a filter is usually a matter of writting trivial shell script See Also: Writing lpd filters. If the program you are using insists on reading a names file as input see the next question. Text mode filters are trivial too (see this HOWTO) unless you want lpr to have a choice of fonts in which case they are slightly harder than trivial. You will probably want to insert and `echo -ne' command at the beginning and end of your filter to set up the font etc to your liking. 3.28 Filters from programs that won't read STDIN ================================================ Some of the programs that are used in writing `lpd' filters are not capable of taking their input from their standard input. For example `dvilj2p' insists on a named file as its input (and what's more expects one with a `.dvi' suffix) so do this: #!/bin/sh ln -s /proc/self/fd/0 /tmp/$$.dvi dvilj2p /tmp/$$ rm /tmp/$$.dvi Note: If it wasn't for the fact that `dvilj2p' adds a `.dvi' suffix you wouldn't need the temporary symlink and could just specify `/proc/self/fd/0' directly. People who use this trick often usually permanently `ln -s /proc/self/fd/0 /dev/stdin'. If you're highly security concious and don't allow access to `/proc' you'll need to create a temporary file. 3.29 Having many filters ======================== Historically the `lpr' command was created to support a finite set of possible file types. You can, in fact, use any of the filters for any reason. If you're never going to use Benson Varian raster files you could use the `-v' switch for GIF files. You could even use `-d' for low res and `-v' for high res. Remember that if you create a filter for a file format that takes a long time to process then your printer may sit idle between print jobs even when there are things in the queue. If you are on a network remember that the filter setups go on the print server. One way to avoid running out of filter options is to define several logical printers in `/etc/printcap' that all point to the same physical one and put each filter in the `if' field of a different printcap entry. This has the advantage that you can set the `PRINTER' enviroment variable to choose your filter rather than having to specify it on the command line each time. One small problem with this is that you have no control over the order in which files from separate queues are printed. Another (and these days more common) way to avoid running out of possible types is to use magic filters. 3.30 Magic Filters ================== Magic filters deduce their input files' types from `magic numbers' (distictive byte patterns at particular offsets). Magic filters are usually perl scripts, shell scripts or C programs that simply identify the file type then call the appropriate non-magic filter. Blatent plug :-) Brian has a generic magic filter bash script that selects the right filter to use based on the output of the `file' command. With a suitable magic filter (and 3 associated non-magic filters) you can do things like: lpr -d file1.dvi file2.div.Z file3.ps file4.texinfo.gz (BTW confguring `lpr' to handle texinfo files is getting a bit silly). This is now on the mailserver or at: `tsx-11.mit.edu:pub/linux/sources/usr.bin/magic-filter-0.4.tar.gz' (Although the release number will possibly change in future). `apsfilter' is a rather easier to use shell script that requires no additional filters and which is pre-configured for HP compatible laser printers. This is also available on the mailserver. An example written in C, which may be easily adapted to most installations is available from the printing mail server as `lpr_if.c'. Magic filters should never specified as `of' as the output filter only gets called once if a number of files are printed without a gap. There are other more subtle problems too using `of'. IMHO (Brian) magic filters as `if' are inelegant as they may prevent you, say, listing a PostScript or nroff file. (Most people disagree with me on this point.) 3.31 Magic Filter Examples ========================== The following is an example of a magic shell script which should take either PostScript or text and deal with it: #!/bin/sh # This is based on a script I received from Scott Doty and which was # written by Keith Walker. Keith's script made use of the fact that # lpd passes options to if: # # -w -l -i -n -h # # to print text out well at any size. This one does not. These options # are also handy if you want to do your own snazzy header page, much # like NeWSPrint from Sun does (although running PostScript through # the display server to get it interpreted is a bit much :) # # # gs will reset the printer anyway, so the this text setup doesn't matter. # setup should include the escape code for \n conversion, if applicable. # printf "" read first_line first_two_chars=`expr $first_line : '\(..\)'` if [ "$first_two_chars" = "%!" ]; then # it's PostScript /usr/bin/gs -dSAFER -dNOPAUSE -q -sDEVICE=??????? -sOutputFile=- - else # it's plain text echo -n $first_line cat printf "\014" fi Note that for the paranoid, shell scripts run as someone other than the user are sometimes a security hole, but this is not the case with lpd filters as the script's environment is not under the control of the potential cracker. 4 Previewing ************ These sections describe various ways to preview things under Linux - that is, how to view them in a way approximating their final form without printing them out. 4.1 ghostview ============= Ghostview, a companion program for `gs', previews PostScript on an X display. It also lets you select individual or ranges of pages from a PostScript document to print using `lpr'. The new version, 1.5, has fixed a few glitches which never bothered me but may make a difference to you. It also calls `gs' with the `-dSAFER' option and has a few more resource and command-line options relative to 1.4.1. The real installation is from: `prep.ai.mit.edu:/pub/gnu/ghostview-XXX.tar.gz' It builds out of the box. Ghostview requires `gs' to work. The new version of `gs', 2.6.x, will use X display fonts in an effort to improve legibility at the low resolutions of a video monitor (a previous failing of this pair relative to commercial display-PostScript based systems). This works very well for me at least, at the expense of exact character positioning (X fonts have different widths). In fact, I thought that Ghostview looks better than Sun's pageview the other day when I looked at the same page in oth programs side-by-side. Ghostview/Ghostscript also has much more intelligent color handling than pageview. You might wish to let `gs' render some Type 1 fonts you install instead of using platform fonts (or the awful fonts `gs' comes with. To do this while in Ghostview (or in any situation involving the X11 driver), place `ghostscript.useExternalFonts: false' in your `.Xdefaults' file, and the platform fonts will not be used. This is part of a message posted to gnu.ghostscript.bug by Tim Theisen : (note that the usual Linux X-server, XFree, is simply an enhanced version of MIT's effort at an i386 X-server (X386), and does contain the X11R5 Type 1 rasterizer which I beleive was contributed by IBM.) Ghostscript now uses the X Toolkit to pick up X Resources. Now ghostscript uses the standard X rules that allow more specific resources to override less specific ones giving users the full power of X resources to control the X11 driver. It also allows system administrators to establish an application defaults file with resources specific to their ghostscript installation. The customization choices mentioned in make.doc have been moved into X resources and are now configured at run time rather than compile time. Sorry, this section of make.doc did not get revised for the 2.6.1 release. If `useBackingPixmap' is set, ghostscript will attempt to allocate a backing pixmap. If one cannot be allocated, ghostscript will issue a warning and ask for backing store instead. (Since there were insufficient resources for a backing pixmap, the X server may not provide backing store either.) Color Handling was totally revamped for gs 2.6. Ghostscript first checks for a suitable standard colormap. If you have static colormap in your X server, it would be best to store a standard colormap property on the root window describing the color layout. Ghostscript will then be able to take full advantage of the device. If you have a standard colormap installed, ghostscript will start slightly faster since it does not have to allocate colors for a cube or ramp. If no standard colormap is available, ghostscript will allocate an RGB cube or gray ramp. Ghostscript tries for a 5x5x5 cube on a color device, and a 128 gray ramp on grayscale devices. It will never ask for more than 1/2 of the colors for a RGB cube or gray ramp. It also takes into account the number of significant bits per pixel. (i.e. It won't ask for 128 gray levels if you only have 16 available.) Ghostscript will attempt to allocate colors that are off the color cube/ramp as the picture is being rendered. Ghostscript will keep track of 256 dynamic colors. After all these are allocated, ghostscript asks the X server directly. The foreground and background color can be set explicitly. This is important for the visually impaired and when using the ghostview widget. Color Resources: 1. `palette'(`Palette'): Default value: `Color'. Other allowable settings: `Grayscale', `Monochrome'. The palette resource is used to restrict the palette used for display. One can set palette to `Grayscale' or `Monochrome' to see how a file would be rendered in grayscale or monochrome on a color display. I use it to avoid dithering of gray- scale figures on a color display with 4-bit DACs. 2. `maxGrayRamp'(`MaxGrayRamp'): Default value: 128. Maximum number of gray levels that ghostscript will attempt to allocate. (It won't try for more than this on an 8-bit pseudo color display even if you set it higher.) Set this lower if you want a smaller ramp and would prefer ghostscript to use dynamic colors. 3. `maxRGBCube'(`MaxRGBCube'): Default value: 5. Maximum number of colors levels that ghostscript will attempt to allocate. (It won't try for more than this on an 8-bit pseudo color display even if you set it higher.) Set this lower if you want a smaller ramp and would prefer ghostscript to use dynamic colors. I believe these values to be a good compromise between dynamic allocation and fall back onto a fairly good color cube for dithering. You can use the foreground and background colors to accomplish "reverse video". However, if you have a grayscale device, it may be better to reverse the gray ramp using the following PostScript code fragment: [{1 exch sub} /exec load currenttransfer /exec load] cvx settransfer The X11 driver now supports native X11 fonts. If you have installed the HP XLFD font extensions into your font or X server. Ghostscript will also be able to use platform fonts at rotations of 90 degrees, with mirroring, and anamorphic scaling. The X11 driver does most if its work silently. You can get it to report when it is using an X11 font by setting the logExternalFonts boolean in your X resources. The X11 driver is setup to use the standard fonts distributed with X11R5. We purchased the Adobe Type Manager and the Adobe Plus Pack. These font packages give all the fonts normally found in the Apple LaserWriter Plus. The X11 driver is setup to handle these fonts as well. (They are a superset of the bitmap fonts distributed with X11.) You may set the regularFonts, symbolFonts, or dinbatFonts resources if you have different fonts available. Each font name must have 7 dashes or it will be ignored. Minimize the use of wildcards to promote faster matching. (I once encountered an X server that took many seconds to do a font lookup when wildcards were carelessly used.) There is a different list of fonts for each common encoding. Regular fonts may be accessed in standard or ISO Latin 1 encoding. The bdf files that are distributed with X11 are in the ISO Latin 1 encoding. This leaves out the ligatures. Luckily, the ligatures are present in the bdf files, but are not given an encoding, essentially commenting them out. You can use the `fixfont' program from the xproof distribution (`Ftp.Cs.Wisc.Edu:/Pub/X/Xproof.Tar.Z', or `Ftp.X.Org:/Contrib/Xproof.Tar.Z') to reencode the bdf files and build X11 fonts that contain the ligatures (i.e standard encoding). If you have the Type1 fonts mentioned above, and you installed the Type1 rasterizer into you font or X server, you can use the appended fonts.scale to name your fonts so that ghostscript can find them. Font resources: 1. `useExternalFonts'(`UseExternalFonts'): Default value: true. This resource controls whether X11 fonts will be used. 2. `useScalableFonts'(`UseScalableFonts'): Default value: true. This resource controls whether scalable fonts will be used. If you have an outline scaler in your X server, you should have this on. If you have an X terminal, you may get slightly better performance with this on. If you have to use the X11 bitmap scaler, turn this off. Fonts scaled by the bitmap scaler look worse than the default ghostscript fonts. 3. `logExternalFonts'(`LogExternalFonts'): Default value: false. Controls whether to report when X11 fonts are being used. The following fonts.scale makes all of the fonts of the Adobe Type Manager and Adobe Plus pack available in standard and ISO Latin 1 encoding. (We were able to purchase the above two packages at an educational discount price of $150.) 70 agw_____.pfb -Adobe-ITC Avant Garde Gothic-Book-r-normal--0-0-0-0-p-0-iso8859-1 agwo____.pfb -Adobe-ITC

Its got a monochrome monitor and a single sided drive...I am very new to this beast and was looking to get a few questions answered if I could... First off, what kind of hard drive interface is this onb the back of the PC? Is it a 25 pin SCSI, or is it some ATARI specific standard? What is a good techie book for this thing? I got no manuals with it, just print master and a couple other Desktop Publishing programs... How expandable is it? I haven't taken it apart yet to see what its made of inside yet, but maybe I should....I don't know what kind of RAM it uses, etc.... I just scoped a few F^TP sites on here for the ST and plan on checking a couple of em out.... -Dan dvac@longs.dr.att.com #! rnews 1249 Path: pagesat.net!decwrl!sdd.hp.com!cs.utexas.edu!howland.reston.ans.net europa.eng.gtefsd.com!MathWorks.Com!noc.near.net!usenet.elf.com!rpi cii3130-04.its.rpi.edu!edgarm From: edgarm@cii3130-04.its.rpi.edu (Marc Edgar) Newsgroups:
