HP rates the Photosmart 7510 at 13.5ppm for black print and 9ppm for colour, both respectable speeds if they're realised. Under test, though, we saw 6.7ppm on the five-page black print test, rising to 10.7ppm on the 20-page one. Print duplex pages, and the speed drops back to 4 sides per minute, as there are noticeable waits for ink drying between sides.
Our black text and colour graphics print produced 4.6ppm, only about half the rated figure, though a single page copy completed in 19s. Photos printed quickly, with a 15 x 10cm image coming through at between 45s and 1:05, depending on source.
When printing duplex, the machine appears to use different inks for front and back sides of pages and to automatically reduce the size of page images, though not by as much as Kodak Heroes do. We can understand that duplex engines may need large page margins, but still feel the driver software should let you know.
Black text print is clean and well formed and draft mode is still very workable, though with some jitters, due to misalignment of successive head passes. Colour graphics are well reproduced, though colours are perhaps not as lively as from some rivals. The colours in our colour copy were particularly close to those in an original and our photo prints were sharp and with good colour, though with some loss of definition in darker areas.
Print is unusually quiet for a fairly fast inkjet machine, peaking at 61dBA during paper feed.
This machine shares the same HP 364 cartridges as the HP Photosmart 5510, with standard and extra large yield versions available. Running costs are therefore the same, with an ISO black page cost of 2.9p and a colour one of 7.3p. Both of these are competitive with most of the machine’s likely competition, other than Kodak machines.
The HP Photosmart 7510 has a novel design, but also a very useful feature set, with duplex print, twin paper trays, wireless connection and both ePrint and Airprint to make it particularly easy to print from. Running costs are good and print quality only drops slightly in comparison with some earlier HP models. Print speeds aren’t all that HP believes, but this machine is still good value at the price.
