My printer is connected via LPT1 to a Windows XP workstation and it is shared to the network. When I configure it on my Windows 7 laptop it prints fine, but when the laptop is used the next day the printer appears offline and it requires to be removed and reinstalled to be available again. The same holds for other workstations and laptops. I can't connect the printer otherwise because of the LPT interface. Is it possible to change this behaviour?
