MUNBYN label printers work with Windows, Mac, Chromebook, iOS, Android, and most tablets. Depending on the model, you can connect via USB, Bluetooth, or Wi-Fi.
No ink or toner is needed. All MUNBYN label printers use direct thermal printing technology—just load the thermal labels and start printing.
Our printers support a wide range of direct thermal labels, including 4×6" shipping labels, 3×2", 2×1", barcode labels, round labels, and custom sticker sizes (40–110mm width depending on the model).
The printer auto-detects label size—no manual calibration required.
Yes. They work seamlessly with Shopify, Amazon, Etsy, eBay, UPS, USPS, FedEx, ShipStation, Pirate Ship, and more.
Yes. For Bluetooth and Wi-Fi models, you can print directly from your iPhone, iPad, or Android device using our app or AirPrint-compatible setup.
Most MUNBYN thermal printers print black only, as direct thermal technology does not support full-color printing.
However, the MUNBYN 405B dual-color thermal printer can print in two colors (e.g., black + red or black + blue, depending on the paper). It requires special dual-color thermal labels to achieve this effect.
For users who want colorful designs without full-color printing, we also offer a wide range of colored thermal labels to customize your branding.
Absolutely. Whether you’re printing shipping labels, barcode labels, price tags, or storage stickers, MUNBYN printers support all daily labeling needs.
Most models use 203 DPI for clear barcodes, shipping labels, and text. Some series offer 300 DPI for sharper logos, product labels, and retail branding.
