I have a Lexmark T520 network printer and each time I install the driver or right clicking Properties on the printer when the printer is install I always have an error message: "A document was sent to the printer before Windows completed the printer driver installation for (path where the printer located). Close your application and try reprinting the document. If you continue to receive this message, reboot your computer to complete installation of the driver." There is no application running who try to send a document to the printer and I try to restart the computer couple of time and doesn't work. I have other PC connected to this network printer and work correctly.
