Printing system for carrying out energy conservation operation
A printer 100 sends status information, ID information and the like to a network device 200 before entering an energy conservation mode in which it is unable to communicate with external devices, so that the network device 200 will respond to a status information request on its behalf. Where a PC 300 requests status information from the printer 100, the network device 200 in which substitute response setting was put in effect responds with the printer 100 status information on behalf of the printer 100. By receiving the status response from the network device 200, the PC 300 can verify that the printer is connected to the network 400. The PC 300 can also send a release order that releases the printer 100 from the energy conservation state so that it can initiate printing.
