Abstract

A network includes plural client processors, a file server and plural printers. Each client processor has memory that stores a printer driver procedure which enables the client processor to interface with at least one printer type. The file server includes memory for storing a most updated printer driver procedure for each printer type coupled to the file server. The file server is responsive to a print request from a client processor to assign a printer to the requesting client processor. The file server then in combination with the client processor determines if a printer driver procedure for the assigned printer in the client processor is identical to a most updated printer driver procedure stored in memory in the file server. If not, the file server enables alteration of the printer driver procedure in the client processor to bring it into coincidence with the most updated print driver procedure. A printer utility is also installed in each client processor and provides the means for automatically determining network status and for indicating to the user whether the network is available or unavailable, and a message indicating the reason for the unavailability.

Claims

1. A network including a file server with plural client processors and plural printers connected to said file server via a network path, said network comprising:

memory in each client processor for storing a printer driver procedure that enables communication between said client processor and at least one type printer;

memory in said file server for storing a library of most-updated printer driver procedures for each specific printer type of said plural printers, each printer driver procedure enabling a client processor to configure an output data stream that is recognized and operated upon by a specific printer type; and

processor means in said file server, responsive to a print message from a requesting client processor, to enable assignment of a printer of said one type to said requesting client processor, said processor means in combination with said requesting client processor further determining if said printer driver procedure for said printer of said one type stored in said requesting client processor is identical to a printer driver procedure for a printer of said one type stored in memory of said file server and, and in response to non-identical printer driver procedures, causing alteration of said printer driver procedure in said requesting client processor to bring said printer driver procedure into coincidence with said most updated printer driver procedure for the printer of said one type.

2. The network as recited in claim 1 wherein said processor means enables assignment of a different printer type other than said one type to said requesting client processor and, upon determining an absence of a printer driver procedure for said different printer type in said requesting client processor, downloading to said requesting client processor from said library, a most updated printer driver procedure for said different printer type.

3. The network as recited in claim 1, wherein said memory in said requesting client processor includes a printer utility procedure which, in combination with said processor means in said file server, enables said requesting client processor to present to a user, a listing of printers on said network.

4. The network as recited in claim 3 wherein said printer utility procedure, in combination with said client processor and in response to a user'"'"'s selection of a printer from said listing, provides a user-visible status level indication that informs the user of availability of said printer selected from said listing.

5. The network as recited in claim 4 wherein said status level indication further informs the user of a status of a network component if said network component indicates a status that prevents use of said printer selected from said listing.

6. The network a recited in claim 5 wherein said network components include a print queue in said memory of said file server, a print server procedure operating in said file server, input/output interface means associated with said selected printer, and said selected printer.

7. The network as recited in claim 6 wherein a status level is determined for each said network component in sequence, and wherein a first status level determined for a network component that prevents use of said printer selected from said listing, controls said user-visible status level indication on said client processor.
