HP claims speeds of up to 33ppm for the HP LaserJet Pro 400 MFP M425dw – shall we just call it the 425? – and we certainly saw a good speed from the machine. Our 5-page text print took 19s, giving a speed of 15.6ppm, while the 20-page document upped this to 23.5ppm. The 5-page text and graphics test, a little surprisingly, gave 16.7ppm, faster than the equivalent text print. So, the top speed isn’t 33ppm, but subjectively, pages come through at a fair lick.

Duplex print is standard and there’s little delay between printing page sides, so our 20-page document printed as 10, double-sided pages, took 1:32, a speed of 13.0spm. Copying is quick, too, with a single page from the flatbed coming through in 10s and five pages from the ADF taking 21s.

The printer’s scanner has twin heads, so duplex pages take little longer to scan than single-sided ones, though printing is slower. A 10-side document still only took 51s, though.

15 x 10cm photos took around 10s from a PC and the front-panel USB slot and 33s using Wireless Direct print. A full-page photo took 41s via ePrint, but this will depend on the speed of your Internet connection.

The prints the machine produced were good, with crisp, clear text reflecting its effective 1,200dpi resolution. Greyscale graphics are a little mottled, but still very workable and, surprisingly, a copy of a page with greyscale content still looked reasonable, when so many copies shift all greys to black, making them barely usable. Photo prints show good greyscales and detail in light and dark areas of each image.

This all-in-one uses a single drum and toner cartridge, available in two capacities. The A version can give up to 2,700 ISO black prints, while the X version is rated at up to 6,900, so you won’t be needing to replace it that regularly. Using the high-yield cartridge gives a cost per ISO page of 2.6p, which is competitive with most rival models in the same price bracket.

Verdict
The HP LaserJet Pro 400 MFP M425dw is an efficient mono laser all-in-one, with useful extras, like duplex print, scan and copy, all of which work well to provide a very useful workhorse for the small office or workgroup. There’s little to grouch about with this machine.
