Image forming system, image forming method and information terminal device
First Claim
1. An image forming system comprising:
- an information terminal device; and
a printing device that is connected to the information terminal device through each of a network and a local line, the printing device operating in a normal mode or, if the printing device is not used for a certain time period, operating in a power saving mode in which the printing device stands by in a lower power state than in the normal mode,wherein the information terminal device comprises;
a local communication controller that controls a local communication with the printing device through the local line;
a network communication controller that controls a network communication with the printing device through the network;
an acquisition unit that obtains a network identifier of the printing device on the network from the printing device by the local communication with the printing device through the local line by the local communication controller; and
a recognition unit that identifies the printing device through each of the network and the local line, and that recognizes the printing device identified through the network and the printing device identified through the local line as one and the same printing device by obtaining the network identifier with use of the acquisition unit,wherein the network communication controller controls the network communication with the printing device through the network according to the network identifier obtained by the acquisition unit, and resumes the printing device from the power saving mode to the normal mode by transmitting print data to the printing device through the network, andthe recognition unit, when identifying a resumption of the printing device identified through the network, recognizes that printing through the printing device identified through the local line is also resumed.

7. An image forming method for an information terminal device and a printing device connected to the information terminal device through a network and a local line, the printing device performing a printing process of image data sent from the information terminal device, comprising:
-
identifying the printing device through each of the network and the local line, obtaining in the information terminal device a network identifier of the printing device on the network through the local line by a communication with the printing device through the local line; and recognizing the printing device identified through the network and the printing device identified through the local line as one and the same printing device by obtaining the network identifier; controlling a communication with the printing device through the network according to the obtained network identifier; resuming the printing device from a power saving mode to a normal mode by transmitting print data to the printing device through the network; and recognizing, when identifying a resumption of the printing device identified through the network, that printing through the printing device indentified through the local line is also resumed. - View Dependent Claims (8, 9, 10)
