How to print the thermal printer test label
- Download the free test label PDF from this page.
- Open it in Preview, Adobe Acrobat or your normal PDF viewer.
- Choose your thermal printer and set the paper size to 4x6 inches or 100x150mm.
- Set scale to actual size or 100%. Avoid fit to page if you can.
- Print one label and check the border, centre marks, scale ruler and barcode lines.
What a good test print looks like
A good print should have an even border, sharp black lines and no clipped edges. If the test label prints too small, your shipping labels may also print too small and carrier barcodes may become harder to scan.
If one side is cut off or the centre marks are shifted, the issue is usually paper size, printer driver settings, label stock size or a scale setting inside the print dialog.
Common thermal printer fixes
- Choose 4x6 inches or 100x150mm as the paper size.
- Turn off fit to page, shrink oversized pages or borderless scaling.
- Make sure the label roll is loaded straight and calibrated.
- Increase darkness if barcode lines look faint or broken.
- Try another PDF viewer if the browser print dialog changes the scale.
When to use LabelChop instead
This test label helps you check the printer. If your actual problem is that Australia Post, MyPost Business, eBay, Shopify or Etsy gives you an awkward A4 PDF, use the free A4 to 4x6 shipping label converter for one-off files.
If you are doing this repeatedly, LabelChop is the automation upgrade: it watches your Downloads folder, detects shipping-label PDFs, crops them to 4x6 / 100x150mm and prints or saves them automatically.
FAQ
What size is the thermal printer test label?
The PDF is 4x6 inches, which is the common 100x150mm shipping label size used by many Dymo, Zebra, Brother, MUNBYN and Rollo thermal printers.
What should I check after printing the test label?
Check that the border is not cut off, the scale reads 100%, the centre marks are aligned, and the barcode lines print sharply without smearing or gaps.
Should I print with fit to page or actual size?
Use actual size or 100% scale where possible. Fit to page can shrink shipping labels and make barcodes harder for carriers to scan.
Does this convert my Australia Post or MyPost label?
No. This page downloads a test label. If you need to convert an A4 shipping-label PDF into 4x6, use the free A4 to 4x6 converter.
