Receipt Printer Test
Engineering preview: usable draft patterns, not a physically validated release. See validation limits.
Experimental P2 preview. Demand validation and physical printer acceptance are pending.
Choose the matching custom media in the printer driver, print at 100% / Actual size, and turn off browser headers/footers. A file cannot set or detect your hardware media automatically.
All native PDFs
Read the test
Compare text sizes, gray steps and the 30 mm line. White space at the edges may be the printer’s physical printable area; do not force borderless output or a cutter operation.
ESC/POS and hardware limits
ESC/POS is a printer command language with model-specific support. This tool supplies browser/PDF test patterns and has no ESC/POS, USB, Bluetooth or network connection. Width selection does not detect the printer or configure its driver.
Before you print again
Does requesting a print mean it printed?
No. The browser can request a dialog, but cannot tell whether you cancelled, sent the job or received paper. Check the preview and the physical result.
Why are there two paper sizes?
Each PDF has a native Letter or A4 page box. Choose the same size in the printer dialog, use Actual size / 100%, and disable headers, footers and Fit to page.
Can this sheet diagnose my printer?
It is a comparison aid. A generic sheet cannot identify a failed part, measure ink remaining, certify colors or replace the manufacturer's model-specific checks.
