4.1Programming Commands
To prompt the Printer for a command sequence, the Printer must first receive a special character called an “attention getter”, which 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.
ASCII | Decimal | HEX | DOS | Attention Getter For | |
Char. | Value | Value | Prompt | ||

SOH | 1 | 01 | Ctrl A | Immediate Commands | |
STX | 2 | 02 | Ctrl B | System Level Commands | |
ESC | 27 | 1B | Crtl [ | Bitmapped Font Loading Commands |

When the Printer receives an "immediate" command it will stop whatever it is doing and perform that command. Commands of all types must be in the following sequence:
