How to use

Install the printer on a stable surface near the point-of-sale terminal, ensuring the side connectors are accessible for cable routing.

Connect the printer to the host device via the USB or RS-232 cable, install drivers or select the appropriate built-in driver on the POS software, and configure paper size and character encoding in the printer settings. Print a test receipt to verify alignment and communication before putting the device into regular service.

Usage recommendations

Use good-quality thermal paper to prolong head life and ensure print contrast. Keep the print head and paper path free from dust and adhesive residues; clean the print head periodically following the manufacturer’s maintenance guidelines. When integrating with legacy systems, confirm serial settings (baud rate, parity, stop bits) match the host device. Store replacement rolls in a cool, dry place away from direct sunlight to prevent paper degradation.
