The first thing you'll notice about the £129 HP Photosmart 6510 e-All-in-One colour inkjet multifunction printer is that it looks better than the competition. But it's also a good multifunction printer, with first-rate output quality and better-than-average print speeds, though ink costs are just average.
The HP Photosmart 6510 e-All-in-One's good looks are partly due to its 3.45-inch touchscreen control panel. The screen is large enough to read and tap easily, too, making the unit as a whole very easy to use. Connectivity falls a bit short: you'll find only SD and Memory Stick card slots behind a front panel, and the machine has no USB/PictBridge port--an unusual omission. The MFP does support USB and Wi-Fi, though, and the installation routine is concise.
HP's bundled software for the HP Photosmart 6510 e-All-in-One is simple to use and supports all of the unit's capabilities, including scanning and copying. It also allows you to scan from the control panel to a PC or a Mac, even if you're using Wi-Fi; some competing models require a USB connection for this function. The Photosmart 6510 supports HP's Web-based apps and remote Web printing, as well as local printing via Wi-Fi from Android and iOS devices.
Paper-handling features for the HP Photosmart 6510 e-All-in-One are fine for low-volume printing and the occasional scan. The 80-page paper cassette has an integrated 20-sheet photo tray. The output tray holds 50 sheets, and the MFP offers automatic duplexing (two-sided printing). You don't get an automatic document feeder here, but you can find an ADF on a slightly higher-priced cousin, the Photosmart 7510. Unfortunately, HP seems to have abandoned the notion that users will ever scan anything thicker than a letter: None of the Photosmart units we've tested have a telescoping lid to facilitate the scanning of pages from magazines or books.

The HP Photosmart 6510 e-All-in-One's ink costs are no better than average.
The standard black cartridge for the HP Photosmart 6510 e-All-in-One costs £10 and lasts for 250 pages (4p per page), while the standard cyan, magenta, and yellow colour cartridges cost £9 each and last for 300 pages, or 3p per page. That's about 13p for a four-colour page.
You can reduce the colour ink costs appreciably with the XL cartridges, which are £17 for 750 pages, or 2.2p per page - almost a penny per page cheaper per colour. We couldn't find an XL black cartridge, so the cheapest full colour page is 10.6p per page.
In our tests, the HP Photosmart 6510 e-All-in-One posted average to slightly above-average print and scan speeds. Text and monochrome graphics exited at a sprightly 7.7 pages per minute on the PC and 7.2 ppm on the Mac--nearly a page per minute faster than the median rate. A half-page photo printed at a slightly above-average rate of about 3.16 ppm, while the same image printed at a slightly below-average rate of about 1 ppm to glossy photo paper. Single-page copies came out around the norm at 3 ppm. Full-page photos printed on the Mac arrived at a rate of about 0.4 ppm--a bit slower than average.
Output from the HP Photosmart 6510 e-All-in-One is very good. At standard settings, text appears sharp and black, though colour graphics tend to be a little grainy on plain paper. The colour palette overall has a slight lean toward yellow, giving graphics a warm and friendly, if not completely accurate, vibe. On glossy photo paper, colour graphics show considerable detail in dark areas and are overall quite nice, with the same warm colour scale.
