Query: Great all-in-one color laser -- works flawlessly in Linux.

I'm a Linux user and wanted a color laser all-in-one. The HP 2840 comes with Windows drivers only, not surprisingly, but is fully supported in Linux. It worked out of the box with cups, using hplip or foomatic drivers. I accessed the CD's only to obtain the configuration documentation, All configuration can be done over http. The printer registered with my dns server automatically as soon as I plugged in into the net. So all functions work in Linux without any need for Windows at all.I also installed the printer on my wife's Windows machine. It works there too of course, but actually took longer and more steps to install than on Linux!The print quality is solid. It's a bit slow to print the first sheet, but overall performance is fine. Color copying/scanning also work well.I'm a happy user.
