A power management apparatus 1 for managing power supply to a plurality of printers 31 to 33 connected to a plurality of host 21 to 23 over a network 5, the power management apparatus 1 comprising: a host-operation-state monitoring module 116 for monitoring whether or not the hosts 21 to 23 are powered on; a host-specific-priority-setting module 111 for setting priority of each of the printers 31 to 33 for each of the hosts 21 to 23; a printer information calculation module 113 for aggregating the set host-specific priorities to calculate priority of each of the printers 31 to 33 by taking the operation state of the hosts 21 to 23 into account; a printer power supply determination module 114 for determining whether or not each printer should be powered on; and a printer power supply control module 115 for remotely controlling power supply to each printer 31 to 33 on the basis of determination on whether or not each printer 31 to 33 should be powered on.
A power management apparatus for managing power supply to a plurality of printers connected to a plurality of hosts over a network, said power management apparatus comprising:
A printer that has power management capability and is connected to a plurality of hosts and one or more printers over a network, said printer comprising:
A power management apparatus for managing through a network power supply to a plurality of printers connected to a plurality of hosts over the network, said power management apparatus comprising:

The present invention relates to a power management apparatus, a printer, a file server, a printing system and computer software and, in particular, to a printing system in which a plurality of printer are shared among a plurality of host apparatuses such as a computers, and a method for controlling the printing system.
An automatic power supply apparatus is proposed in Japanese Patent Laid-Open No. 2000-172474 that automatically detects the end of operation of all computers that use a network printer to turn off the network printer.
Japanese Patent Laid-Open No. 2001-199131 proposes assigning priorities to printers and determining control of power shutoff and energy-saving mode on the basis of the frequency and intervals of printing.
