Summary: We have around 16 of these printers in our school. The networking and the setup is pretty straightforward and the unit has a web-based interface you can use to remotely check the ink levels. The color quality is fairly good for the type of printing we do - mostly simple graphics. It uses two ink cartridges which are fairly expensive if you buy HP, but they are available from other vendors for less.
Summary: HP makes good products in my experience, and this printer has been fine, overall. For those who run Linux, ...well, I'm no expert but I was able to get this printer working without too much hassle; at least HP supports an alternative to the operating system monopoly. HOWEVER, it is annoying that the software makes it so difficult to restrict printing to black-ink-only. And that in that mode, only draft (low-quality) output is allowed (this is true in MS-Windows also.
Summary: A former coworker was using this printer at her desk and when she transferred to another department, I inherited it. She was using Windows XP - I use a Mac. I'm currently running OS X 10.7 (Lion) at work - and using Parallels to run Windows XP in another Window. I can easily print via the Mac OS or via Windows. Like most small deskjet printers, it's a tad noisy when printing.
Summary: In my employer's infinite wisdom, the powers-that-be bought these instead of the higher volume laser printers we used to have. For at least a year, maybe closer to 18 months, this little workhorse has valiantly done it's best to keep up, usually printing 100+ pages a day, every day, if not much more. It's never turned off. I am the one called on whenever there's a problem beyond changing cartridges.
