Black & white printer test
Engineering preview: usable draft patterns, not a physically validated release. See validation limits.
Black & white
Choose Actual size / 100%, the matching paper size, and turn off headers and footers. Do not select Fit to page or borderless enlargement.
Mobile: open the PDF, then use the viewer’s Share / Print command. A download link opens a file; it does not confirm the file was saved.

Pattern preview
Read your result
Check both font samples, horizontal, vertical and diagonal lines, and the 11 gray steps from 0% to 100%. Driver settings and paper can affect fine detail. A pale result does not by itself prove toner or ink is empty.
Read your result
Check repeated marks and their measured spacing with the printer’s internal report. Spacing is a clue, not a part diagnosis. Let the printer cool as directed; do not open or touch a fuser.
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.
