Our Score:


HP's OfficeJet range of ink-jet all-in-ones is well known, but its OfficeJet Pro machines are less famous. The main difference between the two ranges is the print speed of the OfficeJet Pro, which is a result of the separate ink and print head system used in these more expensive machines.

The OfficeJet Pro L7590 is a substantial machine, a good deal wider and higher than HP's cheaper, largely home-orientated machines. Coloured in black and cream, with a predominantly silver control panel, the L7590 looks purposeful and approachable, ideal in a small or home office. It has a 50-sheet Auto Document Feeder (ADF) on top of a standard glass flatbed, working across the width of the machine, and a 250-sheet paper feed at the front. Paper makes its usual 180-degree turn, common in HP inkjets, and is fed out to the top of the paper tray.

For the first time we can remember with an HP printer, there was a minor breakage in transit and one off the hinges for the paper tray lid was broken off. This didn't stop the machine from working, but might indicate the hinge bracket is a bit too flimsy.

There's a duplexer supplied as standard and this clips in at the back of the machine, next to the USB 2 and Ethernet network sockets. Four memory card readers are stacked up vertically, in pairs, in the front right corner of its case.

The most unusual feature of the OfficeJet Pro L7590 is its ink-delivery system. Behind a cover on the left-hand side of the paper tray there's room to slot in the four individual ink cartridges. These are connected by thin, transparent tubes to the print heads, which are also replaceable units. With a claimed service life of 41,500 pages, though, they will be a lifetime component for many customers. Interestingly, each head prints two colours, so black and yellow are paired, as are cyan and magenta.

Charging this whole system with ink is a one-off setup process and takes around 20 minutes. In use, the large volume of ink available means a wider swathe from each head and increases the speed at which documents can be printed. It also means a few more clunking and pumping noises during printing.

HP claims print speeds of 35ppm for black and 34ppm for colour, though it does clearly state that both of these are for printing in draft mode. Just as well, as the normal mode print speeds we saw were around 8.3ppm for black and 5.7ppm for colour. While these are quite fast for real-world inkjet printing, they are an awfully long way off the printed figures. For fun we tried printing our test documents in draft mode, but the black one still took 31 seconds, under 10ppm, and the colour one took 27 seconds, or 11ppm.

Thank you for the useful report. I have one question about the following statement of the duplexer:

"Our 20-page text document took 5:10 seconds to produce, an equivalent of just 0.97ppm."

I would say that 20 pages (=10 sheets of doublesided paper) in 5:10 minutes/seconds has an equivalent of 1.94 doublesided pages per minute. Or do I understand it wrong?

Another question is: is this measured is standard mode (which I expect) or in draft mode?

Thank you very much in advance for your answer!

One more question about hte following statement:

"Copying an A4 page only takes around 20 seconds, though, which is much better, and the copy quality is unusually good, with black text in particular being almost indistinguishable from the original."

Is this the time for a doublesided page or for a singlesided page?

Thank you for you answer!

Last question (for the moderator: maybe you want to combine my 3 comments to 1?):

Is it possible to make doublesided scans out of the ADF (so for example scan 10 doublesided pages in one time)?

I bought an HP L7590 multifunction mashine, had problem with scanning with the feeder a-lot-of-pages-both-sides document as the printer stucks while scanning and "looses" pages (I noticed that every ~10-20 pages, a page was upside down in the output, and it was missing from the scanned document. I changed the mashine with a brand new one (hopefully the store I bought it does this) and the new one had the same problem!!! I send it back, now I have a canon pixma mx850 and I am very happy. Before this, I had the same bad experience with a smaller one HP 6310 (use 2 mashines with the same problem). I WONT USE AGAIN "HP" IN MY LIFE!!!
