I have a home network (wired) with two XP computers and one Win7 computer. There is an inkjet (Canon) shared on one XP computer and a laser printer (Samsung ML-2850) shared on the other XP computer. The network has been setup for years. Two days ago the laser printer will not print from the Win7 computer. The Win7 will print to the inkjet. I have connected the laser printer directly to the Win7 computer and prints fine. I have moved the laser printer to the other XP machine, reinstalled the printer, numerous times, on all the computers. Check the drivers for the laser printer. I am very confused as to what to try next. All of the printers are USB virtual ports. Any suggestions on what to try would be appreciated. The error message I get when I try to print is "unexpected error occurred while printing" real helpful.

Check the network and see if your printer is connected to the correct IP settings or wireless.
