I have 20 computers on a network. One setup as a server with a Brother HL 5440 usb printer on it. The other computer have 2 accounts on them. One for me the Lab Admin. The other is the Lab User. All the computer can see and user the printer on the Lab Admin account but on the Lab User account it can't seem to find the usb port to which the printer has so cannot print. Any help and i will be grateful please. The OS on all computers is Windows 7.
