HP claims speeds of 11ppm for black print and 7.5ppm for colour from the Photosmart 6510, both for ‘laser comparable’ print. If this is what the driver calls Normal print, then it falls a little short of what we saw, mainly due to excessive ink priming and housekeeping before the start of each job.
This regularly took up to 22s and the corresponding speeds started at 5.8ppm on our 5-page text print, rising to 7.3ppm on the 20-page document, still some way short of the claim. We only saw 3.9ppm from our colour print test, too, though printing duplex, the printer managed 4.6 sides per minute, better than some recent HP machines.
A single page colour copy took 35s, again due to extended pre-processing, while 15 x 10cm photo prints took between 1:06 and 1:14, only fair speeds.
Text print from the HP Photosmart 6510 might loosely be called laser comparable, though it's not quite as sharp. It's well up with the best inkjet print we’ve seen from £100 inkjets, though.
Colour print from our sample was slightly banded, as if not all the jets were firing continuously. Photo prints didn't show any of these problems, however, and were both natural and highly detailed.
Online prices for inks continue to vary quite widely, not just from supplier to supplier, but also over comparatively short times from the same supplier. The 364, and particularly the 364XL, cartridges have gone up by over £1 each since we last tested a printer using them, so the page costs have risen correspondingly.
We now calculate an ISO black page to cost 3.2p and an ISO colour page to cost 8.4p, both including 0.7p for paper. Both these figures are little above average for a machine in this price range, but not so far as to make the machine uneconomical to run.
The HP Photosmart 6510 is a practical and well appointed home all-in-one, with comprehensive wireless print options from mobile devices as well as useful, if low capacity, dual trays. Prints are generally good, though they would be quicker if the printer didn't faff about so much before starting each job.
