Introduction
------------

The disk provided with this application note contains PRINTFIX.COM, a
memory-resident utility for computers that encounter printing errors
under MS-DOS version 4.0, 4.01, or 5.0. PRINTFIX disables the extended
error checking that these versions of MS-DOS perform when printing to
a parallel port. Extended error checking needs to be disabled only if
your computer's hardware does not support the hardware checks MS-DOS
is making. You should not install PRINTFIX if you aren't experiencing
printing errors.

Installing PRINTFIX.COM
-----------------------

1. Insert the enclosed PD0495 disk in drive A.

2. Copy PRINTFIX.COM to the subdirectory where your MS-DOS files are
   located. At the command prompt, type the following command and
   press ENTER:

      copy a:\printfix.com c:\dos\printfix.com
      
     NOTE: If you are copying PRINTFIX.COM from a drive other than A,
     substitute the appropriate drive letter for "a" in the above
     command. If your MS-DOS files are located in a directory other
     than C:\DOS, make the appropriate change to the destination path
     in the above command.
     
3. Because PRINTFIX remains memory resident, you only need to load it
   once each time you restart your computer. It is probably best to
   load PRINTFIX from your AUTOEXEC.BAT file. To do this, use a file
   editor such as MS-DOS Edit or Edlin to add the following line to
   your AUTOEXEC.BAT file:

      c:\dos\printfix.com
      
     NOTE: If you start a shell program such as MS-DOS Shell from your
     AUTOEXEC.BAT file, you should place the line that loads PRINTFIX
     before the line that starts your shell program.
