HS-QR34H 3-inch High-Speed Embedded Thermal Printer 250mm/s Multi-Interface Intelligent Cutter Barcode Printing Device

Core Product Advantages

1. Ultra-Fast Printing + Long-Lasting Durability：Adopts thermal line printing technology, 203DPI (8dots/mm) resolution, maximum 250mm/s high-speed output, efficiency far exceeding conventional models; the print head life reaches 100km, the auto cutter supports full cut/partial cut modes (command control). Combined with anti-jam and quick paper jam clearing design, it provides double guarantee of durability and stability, suitable for long-term continuous work.
2. Wide Adaptation + Flexible Paper Supply：Supports 23-82mm wide paper, adapts to 0.053-0.2mm thick thermal paper, with maximum paper roll diameter 120mm and inner diameter 18mm, greatly reducing paper replacement frequency; supports multiple paper types such as receipt paper, label paper and black mark paper, transmissive photoelectric detection supports label seam mark recognition, and narrow flat paper path design is compatible with thick consumables, meeting diverse printing needs.
3. Full Interface + Wide Compatibility：Standard USB (standard Type B), RS232 (DB9 connector), LAN (RJ45) triple interfaces, RS232 baud rate adjustable from 9600-115200bps, meeting different device connection needs; compatible with multiple command sets including EPSON ESC/POS, CPCL, TSPL, JPL, providing Windows drivers, supporting ASCII, GBK, BIG5 and 45 international character sets, adapting to global multi-region use.
4. Rich Printing + Intelligent Control：Supports printing of various 1D barcodes such as UPC-A and EAN13 as well as QR Code 2D barcode, allowing custom characters, downloaded bitmaps and NV bitmap printing, supporting multiple printing modes such as character bold, reverse, 90° rotation; equipped with FEED paper feed key, TEST test key and POWER/STATUS dual indicator lights, supporting power-on self-test and intuitive fault prompts for easy operation; supports intelligent calibration of label mode and fine-tuning of paper tearing position for precise printing needs.
5. Multiple Detections + Stable Protection：Integrates print head temperature detection (thermistor), paper out detection (photoelectric detection), paper near-end detection (photoelectric detection), black mark detection (photoelectric detection), seam mark detection (photoelectric detection) and platen cover open detection (mechanical switch) to monitor device status in real time; the body has a solid structure, buffer design can prevent printing compression, operating temperature 0-50°C, humidity 20%-85%RH, adapting to complex environments with industrial-grade stable performance.
6. Flexible Installation + Convenient Maintenance：The body provides three specifications: with presenter (Type A: 112×190×84mm; Type B: 112×189×84mm) and without presenter (112×164×84mm), embedded installation does not occupy extra space; supports two paper feeding methods: side cover open paper loading and automatic paper absorption, the cutter can be reset by restarting or pressing the open cover button when paper jam occurs, making cleaning and maintenance convenient.

Application Scenarios
