Control Code Command Functions

Introduction

The printer requires a special "attention-getter" character in order to receive a command sequence,
informing the printer that it is about to receive a command and the type of command it will be. Control
Commands, System-Level Commands, and Font Loading Commands have their own unique attention-
getter, followed by a command character that directs printer action.

Attention-Getters

The attention-getters (e.g., "SOH") are standard ASCII control labels that represent a one character control
code (i.e., ^A or Ctrl A). Appendix A contains the entire ASCII Control Code Chart.

Alternate Control Code Modes
For systems unable to transmit certain control codes, Alternate Control Code Modes are available.
Configuring the printer to operate in an Alternate Control Code Mode (selected via the Setup Menu, the
<STX>Kc command or, where applicable, the <STX>KD command) requires the substitution of Standard
Control Characters with Alternate Control Characters in what is otherwise a normal data stream.

Note: Throughout this manual <SOH>, <STX>, <CR>, <ESC>, and ^, will be used to indicate the control codes.
The actual values will depend on whether standard or alternate control codes are enabled for the
particular application.
