Printer Protocol

Introduction

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 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 ASCII Emulation from the EMULATION menu and Proprinter III XL from the Printer Protocol menu, as described in the User's Guide.

The Proprinter III XL emulation provides many configurable parameters. The default parameter values for this emulation are shown in Table 25. 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 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”.
