Questions & Answers

As answered by people managing TestPageLab and Comapi.

Why should a person choose your product over its competitors?

TestPageLab's answer

Because you can check the result. A test page that is only a picture can't tell you whether it printed at the right size; testpagelab's scale bar and calibration lines can, and a guide explains what each fault on the print means and what causes it. The paper generators let you set the spacing in inches or millimeters, the line color and US Letter or A4, then download a PDF that prints true to size. There are no ads, no account and no cookies, and nothing you print is uploaded.

What makes your product unique?

TestPageLab's answer

Every sheet is drawn from measurements and prints at exact size. The printer test pages carry a 100 mm scale bar drawn at exactly 283.465 points, and every graph, lined and staff paper sheet prints a calibration line labelled with its own length, so a ruler tells you in seconds whether your printer shrank the page. The test page PDFs set ink values directly in CMYK, so the cyan sheet asks for cyan ink and nothing else. The methodology page shows the arithmetic and keeps a dated changelog.

How would you describe the primary audience of your product?

TestPageLab's answer

People who print at home, at school or at work. On the printer side: anyone checking a new or misbehaving printer, and IT and help desk staff who need a known-good test sheet. On the paper side: students and teachers who need graph, dot, isometric or lined paper, parents printing handwriting paper, and musicians and music teachers who need staff paper. What they share is needing a sheet that prints at the right size on US Letter or A4.

What's the story behind your product?

TestPageLab's answer

testpagelab started in August 2026 as a single printer test page, built by me around one idea: a test print you can't check is just a picture. Every sheet is generated from measurements by the site's own code, and the scale bar was verified on paper, where the 100 mm bar measured 100.19 mm through Chrome's print path at 100%. Graph, lined and staff paper generators followed, built the same way, so every printable sheet carries a calibration line you can check with a ruler. Every change is listed in a dated changelog on the methodology page.

Which are the primary technologies used for building your product?

TestPageLab's answer

A static site with no third party code. Pages are written in Markdown and built into plain HTML by a Python script with Jinja2 templates. The printer test PDFs come from a standard library Python PDF writer that sets ink values directly in CMYK. The paper generators run on a small JavaScript engine (ES modules) that draws the same sheet as PDF, SVG and PNG, in the browser.

Who are some of the biggest customers of your product?

TestPageLab's answer

None to name: testpagelab is free and has no accounts, so it keeps no customer list.
