Recommendations

Use good-quality thermal paper sized 80×Ø≤80 mm and store paper rolls away from direct sunlight and high humidity to preserve print contrast. For reliable operation, keep the printer’s print head and cutter free of debris and perform periodic checks of cable connections. Configure the POS software to match the character size and line settings supported by the printer.
