  • Patent number: 8804182
    Abstract: A printing control apparatus confirms whether a predetermined free space is present to stabilize an operation of a system. If it is determined that the predetermined free space is not present, the printing control apparatus deletes at least a part of stored print data. In a case where the predetermined free space becomes available by preliminarily performed deletion processing, the printing control apparatus stores print data of a first copy. Then, in the print processing for second and subsequent copies, if print data of a target page is already present, the printing control apparatus skips the processing for generating the print data of the target page.

  • Patent number: 8564822
    Abstract: Print commands are saved in increments of pages, based on usable storage capacity, at the time of printing processing of a first copy, so that page spacing to save the print commands is as uniform as possible. At the time of printing processing of the second copy, the stored print commands are reused and transferred to a printer, and the print commands not stored are generated again. The transferring and generating of the print commands are performed in parallel.

  • Publication number: 20130050750
    Abstract: A print data processing method includes inputting print data and storing the print data in a storage region with a first filter including an interface in a stream format as an input/output interface, sequentially inputting and analyzing parts constituting the print data with a second filter arranged after the first filter and including an interface in a document format as an input/output interface, processing the print data stored in the storage region according to print setting information acquired from the print data as a result of the analyzing by performing the analyzing, and ending processing without inputting all or a part of subsequent parts after the print setting information is acquired by the second filter.

  • Patent number: 8269992
    Abstract: There is provided an image processing apparatus that generates print data for printing by an inkjet printing apparatus, based on a rendering command group that includes a rendering command for a vector image, comprising: a determination unit which determines, for each rendering command included in the rendering command group, whether ink having a predetermined property is to be used; a rendering unit which renders in a first memory a raster image corresponding to a rendering command for ink having the predetermined property is to be used, and renders in a second memory a raster image corresponding to a rendering command for ink having the predetermined property is not to be used; a lossy compression unit which lossily compresses the raster image in the first memory; and a generation unit which generates print data that includes the raster image in the first memory and the raster image in the second memory.

  • Publication number: 20120050803
    Abstract: A print settings screen for instructing creation of form data is displayed as a screen provided by a printer driver. Further, when a form data creation instruction has been received, a screen showing a message indicating that an instruction to complete an operation is required on a print screen provided by an application is displayed in order to execute the instructed creation of form data. Stored, as a form file, is form data created by a creation instruction given on the print settings screen, after the instruction to complete the operation was given on the print screen provided by the application.

  • Patent number: 7945712
    Abstract: A job status monitoring system includes a job output unit configured to output a job to a job managing unit of an operating system. The job is issued in response to a job issue request. A status of the job output to a printer is monitored by a monitoring unit. The monitoring unit controls the job managing unit by monitoring the status of the job. An application or utility determines the status of the job by obtaining information about the job from the job managing unit and performs display control based on the determined status of the job.
