Q:   How can I write a Printer Driver that will send my Laser Printer
     the Setup and Rest commands it needs to print Envelopes?


A:   [This is the Driver called 'LASER ENV' that is shipped with
     V12.2]

     Go to the Add User Defined Printer screen  (F6,S,A keystrokes)
     and add a new printer driver.  Fill in the fields at the top with
     the following information:

          PRINTER ID:     Laser ENV

          DESCRIPTION:    Envelopes on a HP Laser Compatible Printer

          PRINTER TYPE:   P or S 

          SETUP CONTROL:  chr(27)+'&l1O'+chr(27)+'&l3H'

          RESET CONTROL:  chr(27)+'E'+chr(27)+'&l1H'


     Since printer control codes are case sensitive, it is important
     that the letter following the ampersand (the &) is a lower case
     L.  The next character is a number (either a 1 or a 3).  The
     character after the number must be an uppercase letter (either
     an O or an H).

     SETUP CONTROL, (What it does)
     -----------------------------
          The Setup Control sends the control commands in this field
     to the printer each time this printer driver is selected.

          The `chr(27)'is the command that tells your printer that the
     next sequence of letters and numbers is going to be a printer
     control command (in your printer manual it is shown as `ESC'). 
     
          The '&l1O' places the printer in landscape mode (causing it
     to print sideways).

          The '&l3H' tells the printer to pull from the manual feed
     tray and to wait until the manual feed button on the printer is
     pressed.  You may use different commands here depending on what
     your printer is capable of.  For instance, if your printer has
     an envelop tray you could replace this command with '&l6H' which
     would cause it to automatically pull envelopes from the envelope
     tray.  Please consult your printer manual to see what features
     are available with your printer.

     RESET CONTROL
     -------------

          These commands are given to the printer whenever you select
     another printer driver (deselecting this one) or when you exit
     TeleMagic.

          The uppercase 'E' resets your printer back to it's power-on
     defaults and the '&l1H' forces it back to portrait printing
     (printing in the normal direction).
