6 Epson FX-1050 Printer

Protocol

Introduction

This chapter describes the Epson FX 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 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 the User's Guide.

The Epson 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 FX host control codes. An extensive 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 described in the User's Guide.To save the configuration using host control codes, refer to Appendix B, “PTR_SETUP Option”.
