Independent testing
How much independent testing exists for each home printer
Of the 8 home printers we track, 8 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.

Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Home Printers buying guide and the reviewers we cite.
