This must be a hardware problem, but I don't know where to look to fix it. Two printers connected via router to 3 computers. One printer is Laserjet 2200D, other is Epson WP4530.
From Windows 7 computer, both printers are accessible and print. From laptop computer, Epson is also reachable. From this computer, only the Laserjet is accessible and prints. Trying to print to Epson brings up complaint box in lower right of screen, "Printer Applet: Printer 'EPSON' may not be connected." From this same computer, double booting to XP, the EPSON is not accessible either. this printer worked fine up until yesterday. I can also connect to the internet over this same router, from either OS.
I have done the usual reboot process: Turn everything off--all computers, all Ethernet devices, the cable modem. Let them sit for a few minutes, turn them back on, then turn on the
computers. What now?
All suggestions greatly appreciated.
