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.

DPL has been enhanced to accept a 3-character SOH and STX sequence. Easy Control Codes
are always enabled, whether in Standard, Alternate, Alternate 2, or Custom Control Code
Mode. Two types of sequences have been created to meet any application's requirements.
Use these sequences where you normally would use a single SOH or STX character.
