7 Super-Set Programming

Introduction

This chapter describes the super-set commands. Super-set commands affect each of the protocols included in the ASCII Emulation regardless of the printer protocol currently active, except for the P-Series XQ Variant emulation. The commands are sent through the host in the input data stream, and enact the features described in the following subsections.

NOTE: The super-set commands do not affect the P-Series XQ Variant emulation.

The Super-Set Commands

Each printer protocol uses a unique control code sequence to introduce the super-set commands, called the Super-Set Control Code (SSCC):

Table 43. Super-Set Control Codes

Protocol	SSCC	SSCC
	(ASCII Value)	(Hex Value)
P-Series*	SFCC } ;	SFCC 7C 7D 3B
P-Series XQ	N/A	N/A
Serial Matrix	ESC } ;	ESC 7C 7D 3B
Epson FX	ESC } ;	ESC 7C 7D 3B
Proprinter III XL	ESC } ;	ESC 7C 7D 3B

*The SFCC in P-Series is the currently active Special Function Control Code.

NOTE: The super-set commands are briefly introduced in the chapters of this book that describe the control codes for each of the emulations listed above.

In the following subsections, the generic code sequence name, SSCC, is placed before the control code to remind you to enter the correct sequence depending on the printer protocol currently active.
