  • Patent number: 5220674
    Abstract: A local area print server for connection to a printer to form a printing system for servicing printing requests is disclosed. The local area print server both controls the servicing of printing requests by the printer, and in response to printer requests for resources needed to satisfy a printing request, either provides required resources, or obtains the resources from a remote component. A resource manager is provided for receiving resource requests from the printer for resources required to satisfy particular printing requests, and, in response to receiving such requests, forwards the necessary resources to the printer. There is also a status collector adapted for receiving status block messages internally generated by the printing system containing information regarding the changing state of the system and in response to receiving the messages retransmit same to one or more of the other local area print server internal modules that respond to specific printing system status changes.
