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

SUNMI NT320 is a combined label and receipt printer designed for environments that require versatile thermal printing in a compact footprint. The device supports 80 mm paper width and a 203 dpi print resolution, offering clear text and simple graphics for receipts, shipping labels and small-format tags. Multiple connectivity options — USB-C, Bluetooth, Ethernet and WLAN — enable integration with point-of-sale systems, mobile devices and back-office software in retail, hospitality and logistics settings.

Advantages

The SUNMI NT320 delivers thermal printing without ink or toner, reducing operating consumable costs and simplifying maintenance. Its 80 mm width and 203 dpi resolution balance speed and legibility for common receipt and label tasks. Multiple interfaces (USB-C, Bluetooth, Ethernet, WLAN) provide flexible connectivity options for wired and wireless deployments. The combined label and receipt capability allows a single device to handle traditional receipts and small label formats, saving space and streamlining workflows.

Suitable for

• Retail point-of-sale printing of receipts and small promotional or return labels
• Hospitality receipts, order tickets and guest folios in cafés and restaurants
• Small warehouse or shipping stations for printing packing slips and small shipping labels
• Mobile setups where Bluetooth or WLAN connection to tablets and handhelds is required

When it may not be suitable

The SUNMI NT320 is intended for small-format thermal outputs at 80 mm width and 203 dpi resolution; it is not designed for wide-format labels or high-resolution graphic printing. For applications requiring durable thermal transfer printing, heavy-duty industrial labeling, or very high-resolution barcode graphics, a specialized printer type may be more appropriate.

Key specifications

• Print method: direct thermal printing suitable for heat-sensitive paper
• Maximum paper width: 80 mm
• Print resolution: 203 dpi (dots per inch)
• Connectivity: USB-C, Bluetooth, Ethernet (LAN), WLAN (Wi‑Fi)
• Supported outputs: receipts and small-format labels/tags
• Typical use case: retail, hospitality, logistics

How to use

Install thermal paper or label roll according to the paper path indicated on the device and close the cover. Connect the printer to a POS terminal or mobile device using a preferred interface: plug in via USB-C for a direct connection, pair via Bluetooth for mobile printing, or configure Ethernet/WLAN for networked use. Install the appropriate printer driver or app supplied by the system integrator or the SUNMI platform, select the SUNMI NT320 as the target printer in your software, and adjust paper size and print density settings as needed. Perform a test print after setup to confirm alignment and connectivity.

What to consider before purchase

• Confirm that your intended receipts or labels fit within an 80 mm paper width.
• Verify compatibility of your POS software or device drivers with SUNMI printers or available SDKs.
• Decide which connectivity options (USB-C, Bluetooth, Ethernet, WLAN) are required for your environment.
• Consider consumable type: direct thermal media is sensitive to heat, light and abrasion compared with thermal transfer labels.

Usage recommendations

Use high-quality direct thermal rolls or labels designed for 203 dpi printing, store media in a cool, dry place, and avoid prolonged exposure to heat or sunlight to maintain print longevity. For network setups, ensure stable Wi‑Fi or Ethernet connectivity and keep firmware/drivers up to date to preserve compatibility and performance.
