Abstract

The method of the invention enables remote control of a print queue in a network printer which receives print jobs over the Internet from plural client processors. The network printer includes a server procedure which enables transfer of files from the network printer over the network and a browser procedure which enables retrieval of files from client processors over the network. The method includes the steps of: establishing a queue of received print job identifiers; employing the server procedure to provide a first file to a client processor to enable the client processor to transmit a status request concerning the print queue; receiving a message including the status request and transmitting, in response, a second file with queue data to the client processor, the second file further including queue alteration choices; receiving a response message from the client processor with at least one queue alteration value; and altering the queue accordingly. The method further includes the step of responding to a received URL from a scanner, by employing the browser procedure to retrieve a text file identified by the URL.

Claims

1. A method for enabling control of a network printer which receives print jobs over a network from plural client processors, said network printer including a server procedure for enabling transfer of files from said network printer over said network and a browser procedure for enabling retrieval of files to said network printer over said network, said method comprising the steps of:

a) establishing a queue of received print job identifiers;

b) employing said server procedure to provide a first web page to a client processor to enable said client processor to transmit a status message concerning said queue, at least some of said plural client processors having been previously provided with an assigned priority level;

c) receiving said status message and enabling said server procedure to transmit a response comprising a second web page with queue data to said client processor, said second web page further including at least a queue position alteration choice;

d) receiving a further response message from said client processor with at least one queue position alteration value and altering said queue in accordance with said queue position alteration value and said previously assigned priority level of said at least some of said plural client processors; and

e) employing said browser procedure of said network printer to retrieve a print job listed on said queue by a print job identifier.

2. The method as recited in claim 1, wherein said further response message comprises a list of print jobs on said queue and status indications for each said print job.

3. The method as recited in claim 2, wherein said status indications comprise at least one of:

printing status, print job owner, order of jobs to print and expected time to print.

4. The method as recited in claim 1, wherein said response includes queue alteration values for print jobs listed on said queue that comprise at least one of:

deleting a print job, reordering the print jobs, delaying a print job, resuming a print job and changing attributes of a print job.

5. The method as recited in claim 1, wherein said first web page and said second web page are each identified by a Universal Resource Locator identifier.

6. The method as recited in claim 1, wherein said server procedure and said browser procedure operate in accordance with a Hypertext Transfer Protocol.

7. A memory media including procedures for controlling a network printer which receives print jobs over a network from plural client processors, said network printer including a server procedure for enabling transfer of files from said network printer over said network and a browser procedure for enabling retrieval of files to said network printer over said network, said memory media comprising:

a) means for controlling said network printer to establish a queue of received print job identifiers;

b) means for controlling said network printer to employ said server procedure to provide a first web page to a client processor to enable said client processor to transmit a status message concerning said queue, at least some of said plural client processors having been previously provided with an assigned priority level;

c) means for controlling said network printer to receive said status message and to enable said server procedure to transmit a response comprising a second web page with queue data to said client processor, said second web page further including at least a queue position alteration choice;

d) means for controlling said network printer to receive a further response message from said client processor with at least one queue position alteration value and to alter said queue in accordance with said queue position alteration value and said previously assigned priority level of said at least some of said plural client processors; and

e) means for controlling said network printer to employ said browser procedure of said network printer to retrieve a print job that is listed on said queue.

8. The memory media as recited in claim 7, wherein said further response message comprises a list of print jobs on said queue and status indications for each said print job.

10. The memory media as recited in claim 7, wherein said response includes queue alteration values for print jobs listed on said queue that comprise at least one of:

deleting a print job, reordering the print jobs, delaying a print job, resuming a print job and changing attributes of a print job.

11. The memory media as recited in claim 7, wherein said first web page and said second web page are each identified by a Universal Resource Locator identifier.

12. The memory media as recited in claim 7, wherein said server procedure and said browser procedure operate in accordance with a Hypertext Transfer Protocol.

9. The memory media as recited in claim 9, wherein said status indications comprise at least one of:

printing status, print job owner, order of jobs to print and expected time to print.
