Using PostScript: Interactive Mode
PostScript programs are usually generated by application programs
such as word processors. However, PostScript is available for direct
use. In interactive mode, the printer and PostScript function like a
computer. You input a command and this command is carried out.
Then another command is input. The user speaks directly to the
interpreter.
In addition to documenting the use of interactive mode, this chapter
gives a short procedure for changing the persistent parameters of
the printer. Only advanced users or those with equivalent
knowledge should attempt to use interactive mode. It is not for
beginners. You could damage your printer if it is used incorrectly.
Most of the functions covered in this chapter may be accomplished
through the PS Executive Series Utilities program received with
the printer.
NOTE: Only those familiar with the PostScript language or those
with similar programming experience should attempt to
work in interactive mode.
Entering Interactive Mode
The following information is for IBM PC/compatible users. The
first step in using the interactive mode is selecting the serial
interface for communication. PostScript does not echo back to your
monitor unless you are in serial communication. Additionally, the
serial port must be in the PostScript-only mode. Interactive mode
does not work with ESP mode.
1. First, make sure your printer is connected with an RS-232C
null modem serial interface and configure your COM1 port in
your AUTOEXEC.BAT file for the correct protocol, baud
rate, and other options using a mode statement.
