A3 printers are great for printing posters, graphics or large document pages. Find out which A3 printers we'd recommend, and which you should avoid altogether.

In this article
A3 printers let you super-charge your printing sizes for posters, signs or even large photos. But, as they can easily cost over £200, it's important to pick a model that produces great-looking prints.
Here, we point you towards the best A3 printers, with some models under £100. Our recommended A3 models are fast and have low running costs. The same can't be said of all A3 printers - we've also identified three duds you'll want to avoid.
The top five best A3 printers below have gone through comprehensive, independent lab tests, ensuring that they're worth your money.

And here’s three A3 printers to avoid
Choosing the wrong A3 printer can be a costly mistake. They can set you back more than £200 to buy, and poor quality models will thirstily churn through your ink like its water.
Worst of all, at extra-large sizes, there's no hiding from poor print quality. Pick a poor A3 printer and you'll no longer want to show off your favourite photos at poster size.
A bad A3 printer can be slow at turning out text, photos and graphics pages, and you'll usually find the quality wasn't worth waiting for when the prints finally arrive.
A3 printer scanner
While you can still buy dedicated scanners, we don't test them anymore because all-in-one (or 'multi-function') printers - that can also scan and copy - are so widely available.
However, one thing to bear in mind is that while they can print up to A3, many consumer A3 printers can only scan and copy up to A4 in size.
Generally speaking, if you want to scan up to A3 size, you'll need to up your budget for a small office model. But, do bear in mind that spending more money doesn't automatically guarantee getting a higher quality printer or scanner.
