1. A cloud server computing device comprising:
- a processor to;
identify at least one inactive printing device having a persistent connection with the cloud server computing device;
provide the at least one inactive printing device with non-persistent connection information via the persistent connection;
receive a polling message from the at least one inactive printing device via the non-persistent connection; and
send an instruction to the at least one inactive printing device to return to an active state when a job request is available for the at least one inactive printing device.

Abstract
A plurality of printing devices are connected to a cloud server via a persistent connection. The cloud server identifies at least one inactive printing device and provides the at least one inactive printing device with non-persistent connection information via the persistent connection. A polling message is received from the at least one inactive printing device via the non-persistent connection. The cloud server indicates when the at least one inactive printing device is to return to an active state.

14. A method of establishing a connection between a cloud server and a plurality of printing devices, comprising:
-
identifying at least one inactive printing device having a persistent connection with the cloud server; providing the at least one inactive printing device with non-persistent connection information via the persistent connection; receiving a polling message from the at least one inactive printing device via the non-persistent connection; and responsive to receiving the polling message, sending a bitmap to the at least one inactive printing device, wherein the bitmap includes at least one bit to indicate when the at least one inactive printing device is to become active and switch to the persistent connection, and wherein the bitmap is sent via the non-persistent connection. - View Dependent Claims (15, 16, 17, 18)

19. A non-transitory computer-readable medium comprising instructions that, when executed by a processor in a cloud server, cause the cloud server to:
-
identify at least one inactive printing device having a persistent connection with the cloud server; provide the at least one inactive printing device with non-persistent connection information via the persistent connection; receive a polling message from the at least one inactive printing device via the non-persistent connection; and send an instruction to the at least one inactive printing device to return to an active state when a job request is available for the at least one inactive printing device. - View Dependent Claims (20)
