Printer Diagnostic

A free test page for desktop printers. Confirms your browser can open the print dialog, sends a designed test pattern through it, and walks you through a visual checklist on the printed page. Run it on the workstation that has the printer set up.

Read the Printer Test guide for help reading the verdict or fixing each failure mode.

Look at the printed page next to the printer. Answer each question based on what came out of the device.

Did a page physically print on the device (not a PDF on disk)?

Are the registration marks (small plus signs) visible at all 4 corners?

Are all of the color swatches visible and clearly distinct (C, M, Y, K, R, G, B)?

Is the 6pt text row readable without a magnifier?
