6.3Outline of Command System

For details about command system, see the Command Reference separately available.

Commands for this printer consist of a string of ASCII codes and end with "CR" (decimal: 13, hex: 0D). Commands are generally classified into two types, system-level commands and label format commands.

System-level commands are used for system-level operations such as printer status output, sensor selection and memory card maintenance. On the other hand, label format commands are used for definition of printing contents such as character data, bar code data, printing speed, and print density.

System-level commands start with ASCII "SOH" or "STX." Commands starting with "SOH" are required for real-time execution. When received, they are executed immediately even during printing. Commands starting with "STX" enter the buffer area once and then are executed in the order of data reception.

Label format commands end with "CR", following the system-level commands "STX" + "L."
