Abstract
A method and system for enabling a printing program to communicate with a printer relies on a plug and play manager to detect the presence of a printer and send a notification message to the printing program when a device driver registers a new device in the operating system registry. In response to the message, the printing program calls a function in a dynamic port monitor that retrieves the new device registration information from the operating system registry. The dynamic port monitor then creates a port name for the printer and associates it with the physical printer port. The dynamic port monitor also periodically determines whether any excess ports need to be deleted.
