Abstract
An image data processing apparatus shifting to a power saving mode depending on whether a particular process is in progress on an image processing apparatus. A controller examines processes of host computers through a network, and controls a state of supplying power to blocks functioning for an image forming process, the blocks including a rasterizer, a memory, a printer engine, and a compressor/expander.
Claims18
A data processing apparatus for communicating with a plurality of information processing apparatuses through a network and for controlling an image forming apparatus, the data processing apparatus comprising:
- a storing unit that stores a condition for transitioning a state of supplying power of a power source unit to each device in the image forming apparatus;
- a requesting unit that requests each of the plurality of information processing apparatuses on the network to provide at least information about application software that is running on each of the plurality of information processing apparatuses;
- an examining unit that examines that specific application software that has a specific process name is running on each of the plurality of information processing apparatuses based on the information provided from the respective information processing apparatuses through the network, the specific application software being capable of issuing a print job to the image forming apparatus;
- and
- a power control unit that controls the state of supplying power of the power source unit to each device in the image forming apparatus based on a number of the information processing apparatus on which the specific application software is running and the condition stored by the storing unit.
A power control method for a data processing apparatus including, a power source unit for supplying power required to form images, for communicating with a plurality of information processing apparatuses through a network and for controlling an image forming apparatus, the power control method comprising the steps of:
- requesting each of the plurality of information processing apparatuses on the network to provide at least information about application software that is running on each of the plurality of information processing apparatuses;
- examining that specific application software that has a specific process name is running on each of the plurality of information processing apparatuses based on the information provided from the respective information processing apparatuses through the network, the specific application software being capable of issuing a print job to the image forming apparatus;
- and
- controlling a state of supplying power of the power source unit to each device in the image forming apparatus based on a number of the information processing apparatus on which the specific application software is running and a condition for transitioning the state of supplying power of the power source unit to each device.
A storage medium storing, in a computer readable form, a computer program of a data processing apparatus including, a power source unit for supplying power required to form images, for communicating with a plurality of information processing apparatuses through a network and for controlling an image forming apparatus, the computer program comprising:
- program code for executing the steps of requesting each of the plurality of information processing apparatuses on the network to provide at least information about application software that is running on each of the plurality of information processing apparatuses;
- program code for executing the steps of examining that specific application software that has a specific process name is running on each of the plurality of information processing apparatuses based on the information provided from the respective information processing apparatuses through the network, the specific application software being capable of issuing a print job to the image forming apparatus;
- and
- program code for controlling a state of supplying power of the power source unit to each device in the image forming apparatus based on a number of the information processing apparatus on which the specific application software is running and a condition for transitioning the state of supplying power of the power source unit to each device.
