Command Classification

ESC/POS printer commands are classified by functions such as print, character, print position, printing paper, line spacing, panel button, paper sensor, mechanism control, status, barcode, bit-image, macro function, control option, and miscellaneous functions. The classification is called function classification.

ESC/POS printer commands are also classified by sheet and grade. The sheet and grade classification is called matrix classification.

The sheet classification is divided into single sheet commands and multiple sheet commands. The grade classification is separated into basic commands and extension commands.

Basic commands are defined as fundamental printer controls, including print commands and character type selection commands. Extension commands are defined as control codes for functions specific to individual printers. These commands are further divided into mechanical extension commands that relate to additional mechanical functions such as stamp and autocutter units, hardware extension commands that relate to additional hardware functions such as panel button and status transmission controls, and software extension commands that relate to additional software functions such as user-defined and barcode controls.
