HP LaserJet Pro 100 M175a review

Although the LaserJet Pro 100 is a very capable small office colour laser MFP, its running costs are too high


four-pass colour laser, 16ppm print speed, USB, 338x441x421mm

The 1,200×1,200dpi scanner and its driver are identical to those used by most of HP’s other MFPs. It has been overhauled to make scanning more efficient. It’s still very restrictive, though, limiting you to a handful of preset resolutions and providing few image processing or correction features. You can’t disable auto-sharpening, either, which leads to artefacts around areas of fine detail at high resolutions.

There was also vertical banding caused by the movement of the scan head at higher resolutions, and contrast is poor. Scan quality is acceptable at lower resolutions, at least, and 300dpi is more than enough for most office jobs. Colour and mono copies were good, with accurate colour reproduction and balanced greyscale tones.

The LaserJet Pro 100 is a relatively inexpensive laser MFP, and we were pleased with the speed and quality of its prints. However, it’s very expensive to run if you want to print a lot of colour, and we weren’t impressed by its flawed scans. Although it has plenty of features, most small and home office uses will be better off with a business inkjet MFP. The outstanding Epson WorkForce Pro WP-4535 DWF costs £60 more, but it’s much cheaper to run and provides better all-round quality.
