4Serial Matrix Printer
Protocol
Introduction
This chapter describes the Serial Matrix 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.
TheSerial Matrix emulation is very similar to thecode system used by an IBM
Graphics Printer, but contains more features. This emulation enables your
line matrix printer to print files coded for a serial matrix printer. To select the
Serial Matrix emulation mode as the active printer emulation, select A SCII
Emulation from the EMULATION menu and Serial Matrix from the Printer
Protocol menu, as described in the
User's Guide.
The Serial Matrix emulation provides many configurable parame ters. The
default parameter values for this emulation are shown in Table 16. You c an
modify the emulation parameter values in two ways:
•The Serial Matrix host control codes.A n extensive set of Serial Matrix
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 Serial Matrix control codes.
•Theprinter configuration menus. Yo u can modify a subset of the Serial
Matrix emulation parameters using the control panel keys and LCD
display, 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 or reset it to the factory
default configuration. The menu selection for saving a configuration to
memory is described in the
User's Guide.
To save the configuration
using host control codes, refer to Appendix B, “PTR_SETUP Option”.
