Black and White Printer Test Page
Print this free black and white printer test page to check text sharpness, line quality and ink or toner density. It is useful for mono laser printers and for inkjet/color printers when you intentionally print a black-and-white diagnostic, though the causes of weak output differ by technology.

Small text provides a fine-detail reference. Fuzzy, filled-in or broken letters show a print-quality symptom that should be compared with larger text and the printer's own diagnostic page.
2 · Thin and Thick Line Test
Lines from 0.25pt to 4px. All lines should print solid, straight and unbroken.
3 · Toner / Ink Density Blocks
Each block should be clearly darker than the one to its right, with the 100% block printing solid black.
4 · Solid Black Rectangles
Large black areas expose streaks, fading, gray patches and toner scatter.
5 · White-on-Black Sample
White letters should stay open and crisp. Filled-in counters or softened edges can reflect density, media, quality-mode or printer-specific imaging/ink behavior.
6 · Border and Spacing Test
Solid, dashed and dotted borders should print evenly on all four sides of each box.
7 · After-Print Checklist
How to Use This Black and White Test Page
This printer test sheet is designed for anything that prints in black: mono laser printers, all-in-one lasers, and inkjets using the black cartridge or grayscale mode.
Load plain paper
Standard A4 or Letter copy paper is ideal — it's what you'll be printing documents on anyway.
Print in black & white
Click the print button and, if you use a color printer, select black & white or grayscale mode in the print dialog.
Use normal quality
Test at the quality setting you use every day, so the result reflects your real documents.
Inspect in good light
Check the sheet under bright light — subtle streaks and gray patches are easy to miss in dim rooms.
What to Check After Printing
- Small text legibility: if very small text degrades while larger text remains readable, compare the effect at normal quality and on the printer's internal test. Density, media, inkjet nozzle behavior and laser imaging/fusing can all affect fine detail.
- Line continuity: broken thin lines are evidence to investigate. On an inkjet, confirm suspected black-nozzle problems with the built-in nozzle check; on a laser, use the model's print-quality workflow.
- Density separation: if dark steps merge or light steps disappear, note the selected quality/eco mode and compare with the printer's own report before changing hardware.
- Solid black quality: gray blacks, white streaks or uneven fills can involve supplies, settings, media or printer-specific ink/imaging components. The browser sheet alone cannot identify which one.
- Reversed text: filled-in white letters show loss of fine negative detail; compare paper type, quality/density settings and the internal test page.
- Repeating marks: on a laser printer, regular repetition makes a rotating component or contamination worth investigating, but the repeat interval and model documentation are needed before naming a part.
Black and White Testing for Laser and Inkjet Printers
Black output is produced differently by inkjet and laser printers, so the same visual symptom can have different causes. On a laser printer, compare overall density, one-sided fading, repeating defects and toner adhesion with the model's internal print-quality report. Follow the manufacturer's handling instructions before redistributing, reseating or replacing a toner cartridge.
On an inkjet, broken black lines or patchy text can justify checking the built-in nozzle pattern and ink supply, but settings, paper and hardware can produce similar output. Run cleaning only when the model's diagnostic workflow supports it. For deeper tone analysis use the grayscale test page; if text is doubled or shifted rather than simply weak, use the alignment reference and the printer's own alignment procedure.
Frequently Asked Questions
Yes. The sheet is useful for comparing black and gray output on a color printer too. Depending on the printer, driver and grayscale setting, gray or even black-looking output may use black ink/toner alone or a mixture of colorants, so do not assume this browser page isolates one physical black channel.
Gray-looking text can come from draft/eco mode, density settings, paper, low or poorly delivered ink/toner, or printer-specific imaging/nozzle problems. Compare the same page at normal quality and check the printer's built-in report before deciding which cause applies.
On inkjets, nozzle/ink-delivery problems are one possibility; confirm with the printer's own nozzle check before cleaning. On lasers, toner delivery, contamination, imaging components and other print-quality factors can look similar, so use the exact model's diagnostic workflow.
Small text is a sensitive fine-detail reference. If small samples degrade while larger text remains readable, compare quality mode, media and the printer's built-in report; the result does not by itself prove that cleaning or any particular repair is needed.
