Abstract
A method and apparatus for printing over a network where a user at a client device is able to print to a network printer via a server device. The server device includes a print driver that initializes an asynchronous communication channel, sends notification message data to a client device over a network via the asynchronous communication channel, receives data from the client device in response to delivery of the notification message data, and requests user input data from the client device for printing.
