Now an example cloud scanning operation for cloud scanning system 100 of FIG. 1 is described according to one embodiment. User 104 employs user device 102 to send a cloud scan request 1 12 to cloud print service 106. In particular, user 104 employs input device(s) 208 to input a user scan request 1 14 to user device 102. In response, controller 202 generates a cloud scan request 1 16, and transmitter 212 transmits request 1 16 to cloud print service 106. In response, cloud print service 106 forwards request 1 16 to network scanner 108.

FIG. 3 shows elements of a cloud scan request 1 16 according to one embodiment. Referring to FIG. 3, cloud scan request 1 16 includes a print job 302, a device ID 308 that identifies network scanner 108, and a request 312 to transmit the resulting image file 1 18 to cloud document service 1 10.

For example, in various embodiments, some or all of the elements of the process can be executed in a different order, concurrently, and the like.

Referring to FIG. 6, user 104 employs user device 102 to select a scan operation at 602. In response, an application executing on controller 202 of user device 102 gets a list of available scanners 108 registered for user 104 from cloud print service 106 at 604. The application determines which of the scanners 108 are capable of scanning, and displays a list of those scanners 108 to user 104 at 606. User 104 employs user device 102 to select a network scanner 108 from the list at 608. In response, user device 102 formats print job 302 at 610, and submits print job 302 to cloud print service 106 at 612.

Network scanner 108 polls for new print jobs 302 by fetching a list of print jobs 302 from cloud print service 106 at 614. When the list includes a new print job 302 for network scanner 108, network scanner 108 gets the new print job 302 from cloud print service 106 at 616. At 618, network scanner 108 determines that the print job 302 is a scan job 302 using the token(s) 316 in the print job title 314. Network scanner 108 scans the document according to instructions 306 at 620, places the resulting image(s) 124 in an image file 1 18, assigns file name 310 to the image file 1 18, and sends the image file 1 18 to cloud document service 1 10 at 622. At 624 network scanner 108 sends status 120 to cloud print service 106 indicating that the scan job 302 is done.

User device 102 polls cloud print service 106 to obtain status 120. In response to the status 120 indicating that the scan job 302 is done, user device 102 gets image file 1 18 from cloud document service 1 10 using file name 310 at 628, and displays image(s) 124 to user 104 at 630.

FIG. 7 shows elements of a cloud scanning system 700 that includes a legacy scanner and print proxy according to one embodiment. Referring to FIG. 7, cloud scanning system 700 includes a legacy scanner 708 and a print proxy 712. A legacy scanner 708 is a scanner that requires a print proxy 712 to operate with a network. A print proxy 712 is a software component, running on local computing resources, that enables legacy scanners, printers, multi-function printers, and the like, to operate with a network. Legacy scanner 708 can be any device capable of the respective functions described herein, for example such as commercially-available scanners, multi-function printers, and the like. The remaining elements of cloud scanning system 700, namely user device 102, cloud print service 106, and cloud document service 1 10, can be implemented and operated as described above.

Now an example cloud scanning operation for cloud scanning system 700 of FIG. 7 is described according to one embodiment. User 104 employs user device 102 to send a cloud scan request 1 12 to cloud print service 106. In particular, user 104 employs input device(s) 208 to input a user scan request 1 14 to user device 102. In response, controller 202 generates a cloud scan request 1 16, and transmitter 212 transmits request 1 16 to cloud print service 106. In response, cloud print service 106 forwards request 1 16 to print proxy 712. Print proxy generates a legacy scan request 714 responsive to cloud scan request 1 16, and sends request 714 to legacy scanner 708. Legacy scan request 714 can be implemented as a conventional scan request such as a scan request sent by a personal computer to a local scanner or the like.

In response to legacy scan request 714, legacy scanner 708 scans the one or more documents and transmits the resulting image file 1 18 to print proxy 712, which forwards image file 1 18 to cloud document service 1 10. Print proxy 712 also provides status 120 of the scan job 302 to cloud print service 106, which forwards status 120 to user device 102. Referring to FIG. 2, receiver 214 of network interface 206 receives status 120. When status 120 indicates the scan job 302 is done, user device 102 issues a file request 122 to cloud document service 1 10. In particular, controller 202 generates file request 122, for example in response to input from user 104, and transmitter 212 transmits request 122 to cloud document service 1 10.

In this embodiment, the list includes at least one legacy scanner 708 and print proxy 712. User 104 employs user device 1 02 to select a legacy scanner 708 from the list at 808. In response, user device 102 formats print job 302 at 810, and submits print job 302 to cloud print service 106 at 812.

Print proxy 712 polls for new print jobs 302 by fetching a list of print jobs 302 from cloud print service 106 at 814. When the list includes a new print job 302 for legacy scanner 708, print proxy 712 gets the new print job 302 from cloud print service 106 at 816. At 818, print proxy 712 determines that the print job 302 is a scan job 302 using the token(s) 316 in the print job title 314. Print proxy 712 then causes legacy scanner 708 to scan the document according to instructions 306 at 820, places the resulting image(s) 124 in an image file 1 18, assigns file name 310 to the image file 1 18, and sends the image file 1 18 to cloud document service 1 10 at 822. At 824 print proxy 712 sends a status 120 to cloud print service 106 indicating that the scan job 302 is done.

User device 102 polls cloud print service 106 to obtain status 120. In response to the status 120 indicating that the scan job 302 is done, user device 102 gets image file 1 18 from cloud document service 1 10 using file name 310 at 828, and displays image(s) 124 to user 104 at 830.
