I have an HP LaserJet 1012 which is been assigned to the port DOT4_001. I am also attempting to delete the port but each time when I try to delete it, I get the following error message: "Selected port cannot be deleted. The request is also not supported" I am running Win Xp and also encompass with the full administrative rights. I have also removed the printer and reinstalled it but there is the same results toward it..

Does anyone have any suggestions?
