Protocol
Introduction
This chapter describes the Epson FX 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. 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 Epson FX emulation mode, your printer can print files coded for the Epson
FX printer control language. To select the Epson FX emulation as the active
printer emulation, select ASCII Emulation from the EMULATION menu and
Epson FX from the Printer Protocol menu, as described in t he
User's Guide.
TheEps on FX emulation provides many configurable parameters. The default
parameter values for this emulation are shown in Table 34. You can modify
these parameter values in two ways:
•The Epson FXhost control codes. Anextensive set of Epson FX
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 Epson FX control code commands.
•The printer configuration menus. You can modify a subset of the
Epson FX emulation parameters using the control panel keys and LCD
display, as described in the
User's Guide.
A parameter value set by a host control code generally overrides a value set
from the printer's control panel.
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
defaults. The menu selection for saving a configuration to memory is
describedin the
User's Guide.
To save the configuration using host
control codes, refer to Appendix B, “PTR_SETUP Option”.
