Receipt and Label Printer SUNMI NT320 — 80 mm, 203 dpi, Cutter, USB-C, Bluetooth, Ethernet, WLAN

The SUNMI NT320 is a combined receipt and label printer designed for POS and retail environments that require compact, reliable printing of receipts, labels and tickets. It supports 80 mm media width with a 203 dpi thermal print head and features an integrated cutter. Multiple connectivity options — USB-C, Bluetooth, Ethernet and WLAN — enable flexible installation at fixed checkout counters, mobile terminals and back-office stations. The printer is suitable for everyday retail, hospitality and mobile sales tasks where clear text and barcode printing are needed.

Advantages

The SUNMI NT320 delivers 203 dpi thermal printing quality on 80 mm media, ensuring readable receipts and sharp barcode labels. Its built-in cutter simplifies document handling and reduces manual tear-off. Multiple interfaces (USB-C for wired connections, Bluetooth for short-range wireless, Ethernet for networked POS and WLAN for flexible placement) provide deployment flexibility across different store layouts and mobile setups. The compact housing and combined receipt-and-label capability reduce the need for separate devices.

Suitable for

• Point-of-sale receipt printing in shops and small supermarkets
• Label and ticket printing for restaurants, cafes and take-away services
• Mobile sales and field service with Bluetooth-connected tablets or terminals
• Back-office printing tasks where networked printers are required via Ethernet or WLAN

When it may not be suitable

The SUNMI NT320 is optimized for 80 mm thermal media and 203 dpi resolution; it is not intended for high-resolution graphic printing or large-format labels. Environments that require industrial duty cycle printing at very high volumes or thermal transfer labels with special adhesives may need a different printer class.

Key specifications

• Media width: 80 mm
• Print resolution: 203 dpi
• Integrated automatic cutter
• Connectivity: USB-C, Bluetooth, Ethernet (LAN), WLAN (Wi‑Fi)
• Print types: thermal receipt and direct thermal labels
• Use cases: receipts, barcode labels, tickets

How to use

Install the SUNMI NT320 on a stable surface near the POS terminal or mobile device. Load thermal paper or label roll of 80 mm width according to the feed path instructions, then close the cover. Connect via USB-C for direct wired communication, pair with a tablet or phone over Bluetooth for mobile use, or attach to the local network using Ethernet or WLAN for shared access. Configure the printer driver or POS software to match 80 mm paper size, 203 dpi resolution and cutter behavior. Regularly check paper alignment and cutter condition to maintain reliable operation.

What to consider before purchase

• Confirm compatibility of your POS software and device drivers with SUNMI NT320 interfaces (USB-C, Bluetooth, Ethernet, WLAN)
• Verify that 80 mm thermal media and label types meet your durability and adhesive requirements
• Consider expected print volume and duty cycle to ensure cutter and mechanism meet operational needs
• Plan network setup if using Ethernet or WLAN for shared printing

Usage recommendations

For consistent results, use high-quality 80 mm thermal paper or label rolls recommended for direct thermal printing, keep the print head clean and avoid prolonged exposure of printed receipts to heat or sunlight. When deploying multiple units on a network, assign static IPs or reserve DHCP addresses to simplify printer management.
