This happens to me all the time blocked up things waiting to be printed asking for the printer to be installed again - I just clear the waiting items and let the computer do its thing reinstalling the printer but when it asks for the software disc just press the red x each time it asks you to do something and eventually it will work OK. My printer has installed itself loads of times but just links to printer copy 1 and not to the original. I tried uninstalling it and then re-installing it but that did not work either. My sn contacted the printer manufacturer (mine is an HP) and they sent a patch (computer stuff) to stop it happening and then I received a message from them to install something from them to stop the problem also and - touch wood - it has not happened again YET!!! Hope you get yours sorted
