Black & White Printer Test

This test uses only black. It prints a fine 21-step grayscale ramp, a smooth black-to-white gradient, a large solid black density block, a fine-line pattern, and text at descending sizes — ideal for checking a laser printer's toner, a black inkjet cartridge, or general text and line quality without spending color ink.

If the button doesn't work, press Ctrl+P (Windows/Linux) or Cmd+P (Mac) to open your browser's print dialog.

This is an on-screen preview. Your printer, paper, ink or toner level, and print driver settings all affect the final physical result.

How to use this printer test

  1. In your print dialog, set the color mode to "Black & White" or "Grayscale" if you want to conserve color ink (this page uses only black regardless).
  2. Choose your paper size above — the preview updates instantly.
  3. Print at 100% scale on plain paper.
  4. Inspect the page under normal indoor lighting, not direct sunlight, which can wash out light gray steps.

What should the printed page look like?

Grayscale bar

All 21 steps from white to black should be visibly distinct from their neighbors, especially in the lightest and darkest thirds of the range.

Black density block

This large solid block should be uniformly dark edge to edge, with no streaks, faded strips, or a lighter patch anywhere in it.

Fine lines

Every line in the fine-line pattern should print as a continuous, unbroken line of consistent thickness.

Text sample

Even the smallest point size should remain legible, with clean letterforms and no smearing or fuzzy edges.

Common printer problems

Streaks or a faded band running through the black density block

Likely cause: On inkjets: a partially clogged black nozzle. On laser printers: uneven toner distribution or a toner cartridge nearing the end of its life.

How to fix it: Inkjet: run a nozzle cleaning cycle. Laser: gently rock the toner cartridge side to side to redistribute toner, then reprint; replace it if streaking continues.

Light gray steps in the grayscale bar all look the same as white

Likely cause: The print driver's brightness/contrast setting is too high, or the printer is in a low-ink "draft" mode.

How to fix it: Switch off draft/eco mode and set print quality to "Normal" or "Best" in the driver, then reprint.

Fine lines have visible gaps

Likely cause: Clogged inkjet nozzles or a scratched/worn laser drum.

How to fix it: Run our Nozzle Check test to isolate the problem, then clean the print head or inspect the drum unit.

Frequently asked questions

How do I test my printer in black and white?

Print this page at 100% scale. It uses only black, so it works even if you're low on color ink, and lets you check tonal range, density and text sharpness in isolation.

Why are my black and white prints coming out gray or faded?

This usually means low toner or ink, a print quality setting that's too low, or a partially clogged black nozzle on an inkjet printer — check the density block and grayscale bar on this test to narrow it down.

Does this test use color ink?

No — every element on this page is pure black (0% cyan, magenta and yellow), so it won't consume any color ink even if your printer is in color mode.
