POS control codes

POS control codes are the settings that determine which POS printer and cash drawer will be compatible with the POS application. 

 

Commands can be sent to the receipt printer in a number of ways, the most common of which is DecimalNumeral. The below examples use DecimalNumeral, however HEX can be used if desired. All of these commands can be found in the receipt printer manual.

 

The set of control codes defined here is attached to a workstation (or a default may be selected in POS configuration).
