Abstract

Techniques are provided for allowing an application program to print to a new or updated printing device on a network without the user having to perform any updates or reconfigurations that are required with conventional print drivers. The techniques include techniques for retrieving new or updated printing device capabilities data from the printing device on the network, converting the retrieved printing device capabilities to a printer description file, generating print job tickets based on the printer description file, and submitting the print job tickets to the printing device as part of the submission of print jobs to the printing device.

Claims

1. A computer-implemented method for printing to a Web Service-enabled printing device, comprising:

retrieving, from the Web Service-enabled printing device, printing device capabilities data that describes capabilities of the Web Service-enabled printing device;

generating, based on the printing device capabilities data, a printer description file that conforms to the PostScript Printer Description (PPD) file format and includes print job ticket generation information;

generating a print job ticket based on the printer description file; and

submitting the print job ticket to the Web Service-enabled printing device.

2. The computer-implemented method as recited in claim 1, wherein the retrieving printing device capabilities data is performed using Web Service discovery protocol and comprises:

sending a Web Service probe message to the Web Service-enabled printing device at the Web Service-enabled printing device'"'"'s IP address;

receiving, from the Web Service-enabled printing device, a Web Service port number;

requesting, from the Web service-enabled printing device, printing device capabilities data by using the Web Service protocol to communicate with the Web Service-enabled printing device on a port on the Web Service-enabled printing device with the Web Service port number; and

receiving, from the Web Service-enabled printing device, the printing device capabilities data.

3. The computer-implemented method as recited in claim 1, wherein the job ticket generation information included in the printer description file includes PPD extension information that includes one or more of a tree structure, a port number and protocol name.

4. The computer-implemented method as recited in claim 1, wherein:

the printer description file is used to generate a user interface;

the user interface displays the capabilities of the Web Service-enabled printing device; and

user-specified print settings are received through the user interface.

5. The computer-implemented method as recited in claim 4, wherein generating a print job ticket further comprises generating the print job ticket based on the user-specified print settings.

6. The computer-implemented method as recited in claim 5, wherein:

the user-specified print settings are included in print data,

generating a print job ticket based on the user-specified print settings comprises

generating the print job ticket based on print data, and

the computer-implemented method further comprises submitting the print data to the Web Service-enabled printing device.

7. The computer-implemented method as recited in claim 6, wherein the print job ticket and the print data are submitted to the Web Service-enabled printing device as a single print job.

8. The computer-implemented method as recited in claim 7, wherein the print job ticket is included as PDL comment data in the print data.

9. The computer-implemented method as recited in claim 1, wherein the printing device capabilities data retrieved from the printing device includes default print job ticket data and generating a print job ticket based on the printer description file includes generating a print job ticket based on the printer description file and default print settings specified by the default print job ticket data.

10. A computer-readable medium for printing to a Web Service-enabled printing device, the computer-readable medium carrying instructions which, when processed by one or more processors, causes:

retrieving, from the Web Service-enabled printing device, printing device capabilities data that describes capabilities of the Web Service-enabled printing device;

generating, based on the printing device capabilities data, a printer description file that conforms to the PostScript Printer Description (PPD) file format and includes print job ticket generation information;

generating a print job ticket based on the printer description file; and

submitting the print job ticket to the Web Service-enabled printing device.

11. The computer-readable medium as recited in claim 10, wherein the retrieving printing device capabilities data is performed using Web Service discovery protocol and comprises:

sending a Web Service probe message to the Web Service-enabled printing device at the Web Service-enabled printing device'"'"'s IP address;

receiving, from the Web Service-enabled printing device, a Web Service port number;

requesting, from the Web service-enabled printing device, printing device capabilities data by using the Web Service protocol to communicate with the Web Service-enabled printing device on a port on the Web Service-enabled printing device with the Web Service port number; and

receiving, from the Web Service-enabled printing device, the printing device capabilities data.

12. The computer-readable medium as recited in claim 10, wherein the job ticket generation information included in the printer description file includes PPD extension information that includes one or more of a tree structure, a port number and protocol name.

13. The computer-readable medium as recited in claim 10, wherein:

the printer description file is used to generate a user interface;

the user interface displays the capabilities of the Web Service-enabled printing device; and

user-specified print settings are received through the user interface.

14. The computer-readable medium as recited in claim 13, wherein generating a print job ticket further comprises generating the print job ticket based on the user-specified print settings.

15. The computer-readable medium as recited in claim 14, wherein:

the user-specified print settings are included in print data,

generating a print job ticket based on the user-specified print settings comprises

generating the print job ticket based on print data, and

the computer-readable medium further comprises additional instructions which, when processed by the one or more processors, causes submitting the print data to the Web Service-enabled printing device.

16. The computer-readable medium as recited in claim 15, wherein the print job ticket and the print data are submitted to the Web Service-enabled printing device as a single print job.

17. The computer-readable medium as recited in claim 16, wherein the print job ticket is included as PDL comment data in the print data.

18. The computer-readable medium as recited in claim 16, wherein the printing device capabilities data retrieved from the printing device includes default print job ticket data and generating a print job ticket based on the printer description file includes generating a print job ticket based on the printer description file and default print settings specified by the default print job ticket data.

19. An apparatus for printing to a Web Service-enabled printing device, the apparatus comprising a memory storing instructions which, when processed by one or more processors, causes:

retrieving, from the Web Service-enabled printing device, printing device capabilities data that describes capabilities of the Web Service-enabled printing device;

generating, based on the printing device capabilities data, a printer description file that conforms to the PostScript Printer Description (PPD) file format and includes print job ticket generation information;
