3 IBM Proprinter III XL
Emulation
Overview
This chapter describes the Proprinter III XL emulation host control codes.
“Emulation” refers to the ability of a printer to execute the commands of a
particular printer control language. A printer control language is the coding
system used to convey, manipulate, and print data. It contains character
codes and command sequences that configure the emulation. In this manual,
the terms “emulation”, “printer protocol”, and “printer control language” are
synonymous.
In the Proprinter III XL emulation mode, your printer can print files coded for
the Proprinter III XL printer control language. To select the Proprinter
emulation as the active printer emulation, select LinePrinter+ from the
EMULATION menu and Proprinter III XL from the Printer Protocol menu, as
described in the
User’s Manual.
The Proprinter III XL emulation provides many configurable parameters. The
default parameter values for this emulation are shown in Table 14. You can
modify these parameter values in two ways:
• The Proprinter III XL host control codes. An extensive set of Proprinter
III XL control code commands can be sent to the printer from an attached
host computer via the host data stream. Most of this chapter is devoted to
describing the Proprinter III XL control code commands.
• The printer configuration menus. You can modify a subset of the
Proprinter III XL emulation parameters using the printer configuration
menus, control panel keys, and LCD, as described in the
User’s Manual.
Control codes sent from a host system generally override previous settings
that result from the configuration menus.
NOTE: Configuration values selected from the menus or via host control
codes can be saved to the printer’s NVRAM memory so that they will
not be lost when you power off the printer or reset it to the factory
default configuration. The menu selection for saving a configuration to
memory is described in the
User’s Manual.
