TOPRINTRONIX  <file name> / <device or file>

   This program was written by Mark Taunton to allow files produced by
programs such as LAYOUT to be sent to Printronix printers, with the
underlining converted to the format which the printer requires.
The input file must be a text file, and the output can either be a file
which may be sent to the required printer later by the command LIST,
or the name of a printer.

   eg.     TOPRINTRONIX FILE/NEWFILE
   or      TOPRINTRONIX FILE/.LP41

   The following commands are also provided which provide default output 
device names.

   TOLP41  <file>        TOLP15  <file>       TOLP78  <file>
