Summary

Our Score:

8

In its favour, however, the device produces a pretty good draft print, so it should be possible to use this mode for most of the internal documentation in an office. Against it, the noise level from the machine peaks at 68dBA, noisy for a laser and certainly well above what you'd expect from an inkjet device. As is so often the case, it's the paper feed mechanism that makes most of the noise, not the print engine.

Normal mode text prints are clean and sharp, with very little overshoot - and with virtually laser-quality blackness, too. Colour graphics are also very well printed, with regular, dense colour tints and smooth variation from the 1200dpi print heads. Text printed over coloured backgrounds shows a little spikiness, indicating some ink run, but it's still of good office quality.

Photographic prints are also fair, though you can see some of the dot patterns in skies and other areas of continuous tone. It's not that easy to load 15 x 10 centimetre photo blanks, either, as there's no separate photo tray, as there is with some Photosmart models. However, in a busy office environment, printing small photos is a low priority.

The OfficeJet Pro L7590 comes with a duplexer as standard but, like the high-end Canon PIXMA devices, it's awkwardly slow, with an 11 second wait for ink drying between printing of the first and second sides of each page. Our 20-page text document took 5:10 seconds to produce, an equivalent of just 0.97ppm.

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.

With four separate ink cartridges to consider and the possibility of replacing print heads, calculating print costs can be complex. If the machine is heavily used - its duty cycle is quoted at 7,500 pages per month - you could need to replace the heads. However, we reckon an ISO black page should cost around 1.6p to produce and the colour one should come out at around 4.3p.

Despite the machine's high purchase price, its running costs only sit in the middle of the cost range with, for example, some quite inexpensive Canon PIXMA all-in-ones beating it on colour print costs. The high-capacity ink cartridges known as the Value range offer nearly 2,500 black pages and over half that in colour, so maintenance levels should be down with those of low-end colour lasers.

Verdict

Slow duplexing excepted this is a quick ink-jet all-in-one with fair running costs, particularly when you consider the maintenance frequency. Output is easily good enough for office use and draft mode is probably all you need for internal documentation. Thus, if you need a good quality all-in-one with a higher than normal duty cycle, you should certainly consider the OfficeJet Pro L7590.

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!!!
