Which Small Office HP Printers Work Best With Ubuntu?

I’m seeking to purchase a Hewlett-Packard all-in-one device (printer, scanner, copier, fax) that is network-enabled and works with Ubuntu Feisty Fawn 7.04. It must also print color and black-and-white. I realize there is an Ubuntu WiKi listing compatible printers (https://wiki.ubuntu.com/HardwareSupport/) but I’d like to hear from Ubuntu users directly.

Can anyone recommend specific HP small office printer(s) that meet my needs as described above?

I want plug-and-play installation. Once I activate the printer on my office network, I want it to be super-easy for my desktops (Ubuntu/Dell PC, Mac OS laptop and Windows XP/Sony PC) to find the printer on the network and connect to it. No driver headaches. No endless hours searching support forums for guidance.

Thanks in advance for any thoughts.
