All else being equal, we’ll take the printer with the best print quality.

Excellent print and scan quality: Although we think most modern printers produce good-quality results, some generate slightly sharper text, more accurate colors, or better-looking photos.

If manufacturers offer a subscription ink plan, we take that into account as well.

Low operating cost: Ink or toner for black-and-white prints shouldn’t cost more than a few cents per page, and color prints shouldn’t be more than three or four times as much.

Printers that offer single-pass duplex print, scan, and copy are the holy grail.

Duplex printing, scanning, and copying: Two-sided (duplex) printing is a must-have, and if an AIO can print both sides in a single pass, all the better.

Automatic document feeder: A great AIO should feature an automatic document feeder (ADF), because it can automate big scanning and copying jobs to save you time.

However, we did test color laser all-in-ones so that we could recommend a machine for more demanding small-business owners and home users who just don’t want to deal with the frustrations that can come with inkjet ownership.

Printer type: The perfect AIO is probably an inkjet, as laser printers are still too expensive for most people.

If you’re not interested in the extras HP+ has to offer, the older 9015 is a great machine that you might be able to find at a discount. The 9015e replaces our former pick, the OfficeJet Pro 9015, but it’s identical from a hardware perspective the only differences are the longer warranty, the longer Instant Ink trial, and some added software features that are bundled into the new HP+ printing ecosystem. It looks great in any office, thanks to a clean, compact design, and it comes with a two-year warranty that’s twice as long as what you’d get with most competing printers. If you print a lot of photos, you can opt for HP’s Instant Ink program (a six-month trial is included with your initial purchase), which brings the cost of each color page to as little as 2.9¢, including glossies. But it also prints beautifully (and quickly), scans well, has great apps for PCs and mobile devices, and prints for an affordable 2.2¢ per page in black or 8.9¢ per page in color.

The HP OfficeJet Pro 9015e is likely to be the easiest printer you’ve ever had to set up, and that alone is enough to recommend it.
