Install the supplied driver or appropriate POS software drivers (Windows, Java POS, OPOS, CUPS) to enable full functionality. Use the front cover and tool-free removable cutter and print head for quick access in case of paper jams or routine maintenance. Configure barcode and print density settings through the driver or command set as required for receipts and tickets.
Usage recommendations
For reliable long-term operation, use thermal paper within the recommended thickness range (65–75 µm) and avoid exposure of printed receipts to direct sunlight or heat. Enable the printer’s energy-saving and paper-save functions where possible to reduce operating costs. Periodically inspect and, if needed, clean the print head and cutter following the maintenance instructions provided by the manufacturer to maximize service life.
