Andig printers can be delivered in "Modbus Over Serial" connection on a RS422/RS485 physical layer.
It is then necessary to define slave address of the printer and to pass datas using the modbus 16 (10h) function "Multiple Words Write".
Datas to be print are simply transmitted as words (the most significant byte first).
The Modbus 3 (03h) function allows to know the printer status.
