Zebra test label
This test label shows whether your thermal printer is aligned and dark enough: a border at the label's edge, rulers, text sizes, a Code 128, a QR code and a solid block. Pick your label size and density, then send the ZPL to the printer.

Free, with no daily limit. A free account also saves your designs and gives you an API key.
How to read it
The border should show on all four sides: if one is missing, the label is shifted or the width is wrong. The ruler tells you how far off it is. The solid block shows uneven darkness and worn spots on the head: white lines down the block usually mean dirt or dead dots. The barcodes should scan from a phone or scanner.
Printing it
Press ZPL file in the export menu, then send the file to the printer. Printing the PDF through a driver tests the driver as well as the printer.
Questions
Is it free?
Yes: preview and download one file at a time with all its labels, without an account, with no daily limit and no watermark. Paid plans add batches of files, the API and support.
Does it wear out the printer?
No more than any other label.
My printer prints blank labels
Check the media type: direct thermal labels print with no ribbon and thermal transfer needs one. See [blank labels](/zpl/errors/blank-label/).
