A communication system includes a cloud server, a management server, a gateway-enabled device, and a printing apparatus, and these are connected to each other. The gateway-enabled device includes a mode switch that wakes up the device from power saving mode when a HTTP tunneling request is received from the cloud server via a second requesting portion of the management server, a tunneling portion that accesses the cloud server by HTTP tunneling if the request is received via a first requesting portion of the management server during normal operation mode or that does the same after back to normal operation mode if the request is received via the second requesting portion by a method allowing waking up from power saving mode, a receiver that receives a print job from the cloud server having being accessed by HTTP tunneling, and a transfer portion that transfers the print job to the printing apparatus. |

1. A communication system comprising a cloud server, a management server, a gateway-enabled device, and a printing apparatus, the cloud server, the management server, and the gateway-enabled device being connected to each other through the Internet, the printing apparatus being connected to the gateway-enabled device through a communication network,
the cloud server comprising: a print job accepting portion that accepts a print job input from an external apparatus, the print job including a notice of the printing apparatus; an access requesting portion that transmits a HTTP tunneling request to the management server, the HTTP tunneling request to access the cloud server by HTTP tunneling, the HTTP tunneling request being addressed to the gateway-enabled device; and a print job transmitter that transmits the print job to the gateway-enabled device, the print job being accepted by the print job accepting portion, the gateway-enabled device having accessed the cloud server by HTTP tunneling in accordance with the HTTP tunneling request, the HTTP tunneling request being received from the access requesting portion by way of the management server, the management server comprising: a first access requesting portion that transfers the HTTP tunneling request to the gateway-enabled device based on the HTTP tunneling request received from the cloud server; and a second access requesting portion that transfers the HTTP tunneling request to the gateway-enabled device by a method allowing the gateway-enabled device to wake up from power saving mode to normal operation mode, if the HTTP tunneling request is received from the cloud server while the gateway-enabled device is in power saving mode, the gateway-enabled device comprising: a mode switch that switches the gateway-enabled device from normal operation mode to power saving mode and that wakes up the gateway-enabled device from power saving mode to normal operation mode based on the HTTP tunneling request received from the second access requesting portion of the management server; a tunneling portion that accesses the cloud server by HTTP tunneling if the HTTP tunneling request is received from the first access requesting portion of the management server while the gateway-enabled device is in normal operation mode, or that accesses the cloud server by HTTP tunneling after the mode switch returns the gateway-enabled device to normal operation mode, if the HTTP tunneling request is received from the second access requesting portion of the management server while the gateway-enabled device is in power saving mode; a receiver that receives the print job from the cloud server having been accessed by the tunneling portion by HTTP tunneling; and a print job transfer portion that transfers the print job to the printing apparatus specified in the print job, the print job being received by the receiver,wherein the printing apparatus is provided with a job executor that executes the print job, the print job being received from the gateway-enabled device. |
