Purchased two of these wireless printers for use on Ubuntu, Mint and Win7 (UK Amazon listing)
I was expecting some difficulty getting 100% functionality with Linux but imagined it would work eventually.
The actual outcome was that using HPLIP via apt-get to get the latest version (terminal commands below) the Linux machines were up and running in under 5 minutes..100% scan/print/wireless.
Setting up the printer itself using the colour screen took a few minutes, it detected my wireless and accepted the wpa key and auto allocated itself an IP (can be changed from preferences menu).
Both simple scan and xsane find the scanner instantly (installed on mint Julia, Ubuntu 10.4 and 10.10 (//edit: works in 11.04 ubuntu too, see post No#8 )).
+ install GUI toolbox from software center and add printer..Code:sudo add-apt-repository ppa:hplip-isv/ppa sudo apt-get update sudo apt-get install hplip
Windows took considerably longer (win7 home premium & ultimate), over an hour on home premium with the install software very slow and crashing several times..requiring removal and reinstall, ultimate was ok. It also had several of what I consider "trash" applications to tweak photos/purchase HP items/solution centre, though I'm sure someone will make use of them (but NOT on my network).
Print quality seems first class in both windows and Linux from the few tests I've run, scan is a little slow at higher DPI on both Linux and windows, but very good quality.
It also has a print by mail function so you can email a doc or picture directly to the printer from anywhere which works quickly and faultlessly.
Settings can be changed with the printers own screen, hp toolbox and via web page.
This printer has been said by others to be very noisy too...I don't agree with this, it is no worse than many I've owned of various makes.
Ink seems quite cheap at £22.74 for a full set on amazon.
A final word..this is a large printer as the scanner is flat across the top, and even larger once you open the front paper tray.
