Editorial Policy

PrinterTools is a one-person project. All content (guides, tool descriptions, test page documentation) is written by Dan Dadovic. There is no editorial team. This page describes how content is actually created and maintained.

How Content Gets Made

Printer-specific guides (button sequences, menu paths, software names) are written by cross-referencing official manufacturer documentation for each model series. Where manufacturer docs are ambiguous, instructions are tested on physical hardware, primarily HP, Canon, Epson, and Brother printers Dan owns.

Color conversion tools are built on published mathematical standards (sRGB specification, ICC formulae). The conversion library has an automated test suite that runs on every build and verifies output against known reference values. Nearest-match tools (Pantone, RAL, NCS) use Euclidean distance in RGB space against curated databases. The methodology page documents exactly how this works and what the limitations are.

Test page patterns use print-color-adjust: exact to force browsers to print colours faithfully. Patterns have been verified on a small set of printers (HP DeskJet, Canon Pixma, Epson EcoTank, Brother laser) to confirm they surface the issues they claim to diagnose.

What “Last Updated” Means

Every content page shows a “Last updated” date. This reflects the date the page's content was last meaningfully changed, not when a template or layout was updated. If a manufacturer changes their software or a procedure becomes outdated, the affected guide will be updated and the date will change.

PrinterTools launched in March 2026 and is actively maintained. Content updates are driven by user feedback, manufacturer changes, and periodic review, not a fixed schedule.

Editorial Independence

PrinterTools is independently operated. It is not affiliated with, sponsored by, or endorsed by any printer manufacturer. Recommendations and troubleshooting advice are based on Dan's own testing and research. The site does not accept paid reviews, sponsored content, or affiliate commissions.

Display advertising may be enabled in the future. If it is, ads will be clearly separated from editorial content and will not influence recommendations.

Corrections

If you find an error (an incorrect button sequence, a wrong color value, or an outdated instruction), please get in touch. Verified errors are corrected promptly.
