This inkjet printer is fantastic for office graphics and black text, but it misses out on a Best Buy because it’s quite expensive to run. There aren’t that many models to choose from when it comes to A3 printing, so this one will probably be on your shortlist.

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 £600 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.
This all-in-one inkjet model is aimed at printing photos, so it’s no great surprise that print quality is fantastic. It absolutely chugs through ink though – making it hard to recommend it over other A3 printers.

There aren’t that many consumer A3 printers available, but with that limitation in mind, there is no reason to settle for this mediocre machine. Although it prints good-looking black-text documents, everything else about it underwhelms.

You pay big money for this printer, so you'd expect it to be firing on all cylinders when it comes to quality. However, it just isn’t. Print quality is mixed, running costs aren’t exactly cheap. Overall, there are better options available elsewhere.

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.
