Thermal label printer checklist for new online sellers

Overview

A practical checklist for setting up a thermal label printer for marketplace orders.

Before you buy

  • Check that the printer supports 4 x 6 inch (100 x 150 mm) labels.
  • Confirm driver support for your computer.
  • Buy a few spare rolls of the same size.

First setup

  • Install the driver and print a test page.
  • Set the paper size to 4 x 6 inch in the printer settings.
  • Set print scale to 100 percent so nothing shrinks.

Every day

Crop the labels to the right size first, then print the single output file. This keeps the printer from scaling an A4 page down and making the barcode hard to scan.
