How to Print Price Tags and Barcodes From Your Phone With a 58 mm Thermal Printer

Handwritten price tags look untidy, smudge easily and take time to redo every time a price changes. A small Bluetooth thermal printer fixes that for shops that do not want a computer at the counter. Here is how the workflow looks with the mini printer we make at PackForge.

What you need

  • A smartphone with the printer's companion app
  • The mini Bluetooth thermal printer (58 mm paper width)
  • 58 mm direct thermal rolls (10 rolls ship in the box)

Step by step

  1. Charge and switch on. The printer runs on a 750 mAh rechargeable battery and charges over USB Type-C, so a phone charger or power bank works.
  2. Pair over Bluetooth 5.0. No Wi-Fi network or laptop is involved; the phone talks to the printer directly.
  3. Design the label in the app. Add the product name, price and, if you need one, a barcode or SKU code.
  4. Print. Output is 304 DPI black monochrome, sharp enough for small fonts and scannable barcodes.

Why direct thermal suits a shop counter

Direct thermal printing uses heat on special paper, so there is no ink, toner or ribbon to buy or replace. The only running cost is paper.

Know the limits

  • Labels are 58 mm wide, so full 4 x 6 inch courier labels need a wider printer.
  • It prints black only, so no colour logos or photos.
  • Plain paper will not work; only thermal paper darkens.

Typical uses

Price tags, shelf strips, barcode and SKU stickers, order numbers and short "fragile" tags.
