Abstract
A method for dynamically synchronizing configuration information between a printer and an attached accessory. In one embodiment, the printer firmware creates a configuration change object that is immediately incremented any time a configuration parameter is changed. The accessory periodically queries the printer to determine if the configuration change object has been incremented, and, if so, the accessory re-reads and stores the new printer configuration along with the new configuration change object. In a second embodiment, the printer sends out a notice to the accessory that the printer configuration has changed immediately after the change is made, rather than accessory periodically asking the printer if the configuration has changed.
