Connect the printer to your POS or terminal using the chosen interface (USB, serial, parallel or Ethernet) and configure network settings if using Ethernet (DHCP supported). Load paper with the simple drop-in mechanism, ensure the sensors detect the roll and close the rear cover.

Regularly check ribbon/ink and paper status indicators to avoid interruptions.

Usage recommendations

Use standard thermal-compatible or recommended impact paper rolls within the specified width and maximum diameter to ensure consistent print quality and to avoid sensor or feed issues. For kitchen or bar environments, enable the internal buzzer for immediate notification of completed prints. Schedule preventative checks of the print head and platen, and keep the paper path free of debris to maximize the rated mechanism life.
