Margins and borderless printer test

Engineering preview: usable draft patterns, not a physically validated release. See validation limits.

Read your result

Inspect the 0, 3, 5 and 10 mm frames and corner marks. A missing edge can be the printer’s normal unprintable area. Borderless enlargement changes dimensions; record its setting.

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.
