3P-Series XQ Printer
Protocol
Introduction
This chapter describes the P-Series XQ emulation host control codes.
“Emulation” refers to the ability of a printer to execute the comm ands of a
particular printer control language. A printer control language is the coding
system used to convey, manipulate, and print data. Carriage Return, print
quality, character attributes such as bold and underline, margins, and tabs are
typical functions selected by printer control language codes. In this manual,
the terms emulation, printer protocol, and printer control language are
synonymous.
The P-SeriesXQ emulation was devised for a series of Printronixprinters
manufactured between 1974 and 1991, but no longer available. This
emulation enables your printer to emulate Printronix P300 and P600 printers
with A7/B10 boards. To select the P-Series XQ emulation mode as the active
printer emulation, select ASCII Emulation from the EMULATION menu and
P-Series XQ from the Printer Protocol menu, as described in the

User's

Guide.

The P-Series XQ emulation provides many configurable parameters. Th e
default parameter values for this emulation are shown in Table 12. You c an
modify the emulation parameter values in two ways:
•The P-SeriesXQ host control codes. An extensive set of P-Series XQ
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 P-Series XQ control codes.
•The printer configuration menus. You can modify a subset of the P-
Series XQ emulation parameters using the control panel keys and LCD,
as described in the

User’s Guide.

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. The menu selection for
saving a configuration to memory is described in the

User’sGuide.

To
save the configuration using host control codes, refer to Appendix B,
“PTR_SETUPOption”.
