I have an HP 842C attached to a Win XP Home machine. The XP is on a wifi network, with a laptop running XP Pro. I also have a Win98 hardwired into the network. Both XP machines can share printers no problem. Issue is when I try to install the printer and print from the Win98 machine. Network neighborhood sees the printer on the XP machine, installs fine. Just won't print. Try a testpage, immediate Cannot Print message comes up. Any clues?
