  • Patent number: 8620172
    Abstract: An image forming apparatus for outputting a printed product includes a fusing unit, an image forming control unit to receive print data and print attribution information for printing the printed product; and a print engine including a fusing controller to control a fusing temperature of the fusing unit. The print engine outputs the printed product using a fusing temperature designated by the print attribution information. The fusing controller determines a target fusing temperature for the fusing unit by comparing a first fusing temperature and a second fusing temperature. The first fusing temperature is used for a most recently conducted fusing process. The second fusing temperature is designated by the print attribution information. The fusing controller determines the target fusing temperature to the first fusing temperature or the second fusing temperature depending on the number of colors required for printing the printed product.

  • Patent number: 8488166
    Abstract: A printing system including a plurality of host devices and a plurality of printing devices connected. The printing system includes: a storage unit; a first storage processing unit for storing, in the storage unit, a print status of a print job; an information updating unit for monitoring the plurality of printing devices and updates the execution status identification information stored in the storage unit; and a job management unit for determining, based on the print status, whether the print job is to be executed on the one printing device. When a processing request for the print job is sent from another host device while the printing process for the print job sent from the one host device is suspended in the one printing device, the job management unit allows the one printing device to execute the print job sent from the another host device.

  • Patent number: 8194272
    Abstract: When a printing device is in a state in which a printing process of a print job including at least one print data and a series of process commands from a host apparatus cannot be executed, a printing processing unit transfers a printing right corresponding to the print job that is left unprinted to other printing device. When the printing device is in a state in which the printing process can be executed and if the printing right corresponding to the print job that is left unprinted is transferred to the printing device from the other printing device, the printing processing unit executes the printing process.

  • Patent number: 8189221
    Abstract: In an image forming device, when a priority of outputting input data determined by a priority determining unit is higher than a priority of in-process data during image expansion performed by one of PDL interpreter units, a PDL control unit determines whether the one of the PDL interpreter units supports an interruption process, and an output sequence changing unit changes an output sequence stored in an output sequence storing unit such that, when the one of the PDL interpreter units supports the interruption process, another of the PDL interpreter units performs image expansion of the input data earlier than the image expansion of the in-process data, and when the one of the PDL interpreter units does not support the interruption process, another of the PDL interpreter units performs the image expansion of the input data later than the image expansion of the in-process data.
