DATA PROCESSOR, DATA PROCESSING METHOD, AND CONTROL PROGRAM

摘要

A printer 301 as a peripheral device notifies a proxy response server 200 connectable to a LAN 101 during transition to a sleep mode from a normal data processing wait state of sleep transition request. After the proxy response server 200 receives a sleep mode transition request, and when the proxy response server 200 receives a sleep release request from any client PC 100 in which a proxy response server 200 is connected to a LAN 101, a sleep mode is released at a sleep release request from the proxy response server 200.
