In our testing, the copy quality was quite good. You can scan to a variety of file formats, including PDF, JPEG and TIFF. The scanner only reads one side of the page, but it can both scan and copy. It also has an automatic document feeder, so you can run multipage documents through its scanner.

The HP OfficeJet All-in-One 250’s paper input feeder holds up to 50 pages of standard paper, which is the largest capacity offered on a mobile printer. If you want to make printing even more affordable, HP also sells high-capacity, XL versions of its ink cartridges, bumping up the page yields to 600 and 415 pages, respectively.

In any event, HP offers a pretty good page yield for each cartridge, with a standard black cartridge producing some 200 pages and the tri-color cartridge lasting 165 pages, which is pretty good value for money when you consider that a cartridge usually costs around $18-$24. We don’t recommend tri-color ink cartridges on normal printers, but in a compact printer, it’s par for the course. However, you'll note that Primera rates the Trio as the world's smallest all-in-one printer, and we certainly can't remember seeing anything with more petite proportions.HP OfficeJet All-in-One 250 review: FeaturesĪs an inkjet printer, the HP OfficeJet All-in-One 250 uses a two-cartridge system, with one cartridge for black ink and the second for cyan, magenta and yellow ink. The printer measures 29 x 4.8 x 16.51 cm (11.4 x 1.8 x 6.5 in), which is certainly very small, though Brother's Pocket Jet 6 printer measures just 25 x 5.5 x 3 cm (10.04 x 2.17 x 1.18 in). A4 is fed from the primary 10-sheet feeder, while postcards, invitations and photos can be printed using the secondary 10 x 15 cm (4 x 6 in) rear feed. It can print on up to A4-sized paper at up to 4,800 dpi. The Primera Trio is an inkjet printer, and takes color or monochrome cartridges. The Primera Trio weighs 1.2 kg (2.7 lb), is compared by the firm to the size of a hardcover book, and can run from an optional battery pack. Unless you add '3D' to the mix, printers aren't often worth getting very excited about nowadays, but printer manufacturer Primera Technology has revealed what it reckons is the world's smallest and lightest all-in-one printer at this year's CES.
