The LaserJet P1566 has what HP calls Instant-on Technology, which means it doesn't have to wait to warm its fuser up before starting a print job, when it's been asleep. In fact, it's one of the fastest printers we've seen to start a print job from being fully asleep. It's not much more than five seconds before the paper starts to move.
With this quick start, which will particularly benefit anybody who uses a printer occasionally for short jobs, you're likely to see something close to the claimed 22ppm print speed. Although our 5-page document took 23 seconds – a speed of 13ppm – the longer, 20-page job gave a speed of 19.1ppm, not a long way off the headline figure. The 5-page text and graphics document came through in 15ppm, another good result, and a 15 x 10cm photo print completed in a very impressive seven seconds.
Mono laser print has long been one of HP's strengths and the text output from this printer is hard to fault. Characters are well formed with no signs of jagged edges to curves or diagonals and clean, bold print not marked by any toner spatter.
Although the default resolution is 600dpi, HP enhances this up to a 1,200dpi-like print, which stands the machine in good stead for printing graphics. Greyscale fills aren't quite as smooth as we would like, but there are enough grey shades to do a colour original justice. The only problem we saw with a graphical output was spiked edges to some of the graphic borders.
Our test photo print gave surprisingly good detail in the difficult darker areas of our test image, but there was still some unevenness to areas of smooth texture, in this case the sky in the photo.
There's just one version of the combined drum and toner cartridge, with a capacity of 2,100 pages, and the cheapest we could find this for was just over £55. This gives a cost per page of 3.5p, including 0.7p for paper, which is competitive with other HP lasers and pretty much in the middle of the field, when compared with rival machines in the same price range.
HP has sorted the principles of mono laser print and can produce consistently good quality print at good speed, even from a printer costing well under £150. Here, it has concentrated on easy installation and quick start-up, which improves overall performance on any printer that isn't in constant use. The LaserJet P1566 would be a good choice for any small or home office with a reasonable workload of general business documents.
