SetPRN by JJO

     PURPOSE

     SetPRN is intended to be called from a batch file (see below) to
     set printer parameters prior to calling a print spooler. SetPRN
     always sets the printer's perforation skip function to 5 lines.

     If no printer options are selected, SetPRN defaults to Epson and
     should be compatible with most printers.

     USAGE

     Syntax: SETPRN [?][options]

     Parameters: [] optional and <> required, where a parameter is a
     character or a string (no spaces). Parameters must be separated
     by one or more spaces where so shown above.

                              Parameter List

     ? means display this file (/? is also acceptable).

     Options, one or more of (any order and case);
        /B    forces black & white display.
        /L:n  sets line spacing (n = 6, 4 or 8 lpi).
        /M:n  sets margin (n = 0..10).
        /P:n  chooses printer port (n = 1..2).
        /Q:c  sets print quality (c = (D)raft, (E)mphasized or (L)etter).
        /T:c  sets type style (c = (P)ica, (E)lite or (C)ompressed).
        /U:c  selects printer (c = (E)pson, (D)ataproducts or (I)BM.
              The defaults are listed first.
              If M, Q or T are used for other than an Epson (or clone)
                 then enter printer code.

     NOTES

     If there are command line errors or the specified printer is
     unavailable, SetPRN will halt with an error message. Error messages
     are beeped and left on the screen when SetPRN terminates.

     Planned upgrades include automatic generation of the print spooler
     command line from file and option parameters supplied to SetPRN.

     This file amy be printed via MerPRN or by typing at the DOS prompt
     TYPE SETPRN.TXT > PRN.

     BATCH FILE USAGE

     SetPRN is designed for execution from within a batch file; hence,
     test for an error code returned by SetPRN and, if found, stop batch
     execution until the problem is cleared. This can be done by
     inserting a line like this after each call to SetPRN:

                          IF ERRORLEVEL 1 GOTO Error

     where "Error" can be any line(s) which cause the batch process to
     terminate. See the sample batch file SetEx.Bat.
