Abstract
In a method of controlling the power state of a peripheral device, the peripheral is changed from a first power state to a second power state in response to communications across a network connected to the peripheral indicating that a user is proximately located to the peripheral. A user may be determined to be proximately located to the peripheral by monitoring communications across the network to detect traffic that is associated with a user logging onto a computer that can utilize the peripheral, by discovering a wireless terminal that is associated with a user and which is proximately located to the peripheral, by receiving information from a cellular communication network across the network that indicates that a user of the peripheral is proximately located to the peripheral, and/or in response to a time of day and/or day of week/month schedule.
