It is indeed a windows printer, but thanks to the good work of Tim Norman at http://www.rpi.edu/~normat/technical/ppa/index.html you can use it with linux. He wrote a nice utility called pbm2ppa which converts postscript and ascii to the ppa language, used by HP deskjet 710, 720, 820 and 1000 series. I just found this out today. It works just great!
