Setting Up Your Printer

2.5 Programming Commands

In order to be ready for a command sequence, the Printer must first

receive a special character called an “attention getter” that informs

the Printer that it is about to receive a command and the type of

command it will be. Immediate Commands, System-Level

Commands, and Font-Loading Commands each have their own

attention getter. The attention getter character is followed by a

command character that tells the Printer what action to take.

Table 2-5 Attention Getters

When the Printer receives an Immediate Command it will cease

whatever it is doing and perform that command. Commands of all

types must be in this sequence:

1. Attention Getter

2. Command Character

3. Parameters that must be entered by the user (if any).
