Part IV
Printer Software
Commands
Introduction
Printer software commands are an alternative to the
printer keypad for controlling some printer functions. By
using these commands you can by-pass the printer's key-
pad when you wish to change fonts, emulation mode, page
orientation, paper source, paper size, or number of copies.
Some of the software commands explained here have no
equivalent keypad sequence (such as "Redefining Transla-
tion Tables").
Each of these commands begins with an "ESCape" - a
special character that tells the printer "a command fol-
lows." Do not confuse the ESCape character with the
I

key on your computer keyboard. The ESCape
character cannot usually be "sent" to the printer by just
pressing a key on the computer's keyboard.
The examples in this section illustrate how to send the soft-
ware commands to the printer using BASIC. If you use
your word processor or applications package exclusively,
you will use a different method when sending commands
to
the printer. Refer to your software package's instruc-
tions for using the ESCape character. Your laser printer
also provides a method for substituting the "tilde" charac-
ter ("') as the special character signalling the beginning of
a software command. Refer to Part III of this manual for
information on using Group 1 Option A.
