Black & White Printer Print Test
Run a black & white printer print test to check grayscale accuracy, toner/ink coverage, and text sharpness on mono and laser printers — print it directly from your browser in seconds.
Before you print: open the print dialog (Ctrl/Cmd+P) and enable Background graphics under "More settings" so the solid black block and gray bars print correctly instead of blank.
11-step grayscale gradient (100% black to white)
Text sharpness, several sizes
Fine line pattern (banding check)
Solid black fill (full toner/ink coverage)
What to Look For
Smooth grayscale steps
Each of the 11 gray bars should be a distinct, even shade. Streaking or an uneven bar usually means low toner or a clogged nozzle.
Crisp small text
The smallest text line should still be legible. Blurry or feathered letters point to a dirty print head or misalignment.
No line banding
The fine-line pattern should print as clean, evenly spaced lines — gaps or fuzziness suggest the print head needs cleaning.
Even solid black
The solid black block should be fully opaque edge to edge, with no light streaks or faded patches from low toner.
Frequently Asked Questions
How do I run a black and white printer print test?
To run a black and white printer print test, open this page, press Ctrl+P (Cmd+P on Mac), enable "Background graphics" in the print dialog's more settings, choose your printer, and print — no download needed.
Why does the solid black block print gray or streaky?
This is the most common sign of a low or unevenly distributed toner/ink cartridge. Try shaking a toner cartridge gently, or run your printer's cleaning cycle for inkjets, then reprint.
Can I use this test page for a laser printer?
Yes — the grayscale steps, text samples, and solid black fill work the same way for checking toner coverage on laser printers as they do for inkjet.
