I have a network with windows xp workstations and a Windows 2003 server domain controller. One of the workstations has a printer attahced to it which is shared over the network. Everything works fine until the computer with the printer attached is off and on again. Every time it happens, it loses communication with the printer, therefore nobody can print. Every time I have to uninstall de printer driver and reinstall it again and it began to work again. The computer with the printer attached is running Windows XP Professional SP3. The printer is an HP 1020.
