An apparatus includes a combination unit configured to, in a case where print is print on a second sheet of paper out of two sheets of paper into which mark information for gradation adjustment is divided on a two colors-by-two colors basis, and a type of paper of the second sheet of paper is the same as a type of paper of a first sheet of paper, and in a case where a chart insertion job is not requested or the print is based on the chart insertion job, combine the mark information for gradation adjustment for remaining two colors or four colors with a print image in accordance with a size of the second sheet of paper.

Apparatus and method

An image processing apparatus capable of, even both of reservation printing and pre-printing paper sheet confirmation are set for one print job, preventing a printing process from substantially being halted due to a confliction between these two settings. The image processing apparatus is capable of generating a print job, a time request and a print medium confirmation request. The image processing apparatus performs: a first process, which exclusively generates one of the time request and the print medium confirmation request, generates the print job including the generated one request, and performs a process corresponding to the generated one request prior to printing based on the print job; or a second process, which generates the time request and the print medium confirmation request, generates both of the two request, and exclusively performs one of the two requests prior to printing based on the print job.

Image processing apparatus capable of exclusively setting multiple settings, method therefor, and storage medium

There is provided a control method for an image reading apparatus including a document conveyance unit configured to convey a document, a first reading unit configured to read a first surface of the document conveyed by the document conveyance unit, and a second reading unit configured to read a second surface of the document conveyed by the document conveyance unit, includes setting a two-sided reading mode for reading the first surface and the second surface of the document, and starting initial adjustment operation of the second reading unit in response to setting of the two-sided reading mode.

Image reading apparatus configured to make adjustments when set to read two sides of a document

A control method for controlling a printing system that includes selectively executing an inline job and an offline job, where the inline job is for executing post-processing on a sheet printed by a printing apparatus by using a post-processing apparatus and the offline job is for executing post-processing on a sheet without executing printing by the printing apparatus by using the post-processing apparatus. The method includes detecting that a sheet has been set in a paper feed unit, setting whether to execute an offline job that uses the sheet if the sheet is detected as being set in the paper feed unit, and controlling the post-processing apparatus to automatically start post-processing corresponding to the offline job in a case where both the system is set to execute the offline job and the system detects that the sheet has been set in the paper feed unit.

Printing system, method for controlling the printing system, and program

An image forming apparatus comprises a printing unit that performs a double-sided print for a plurality of pages and a deletion unit that deletes data of a page that the printing unit prints. The deletion unit, in a case where a page printed last by the printing unit out of the plurality of pages is an odd page counting from the first page in a print order, does not delete but stores data of the page printed last.

Image forming apparatus, image forming method

When a job that is set so as to execute binding processing at a first binding position is being executed and this job is then interrupted, a request for changing a position of the binding processing from the first binding position to a second binding position is accepted in a state where the job is interrupted. It is determined whether or not an orientation of a print target image is to be changed in order to change the position of the binding processing from the first binding position to the second binding position in accordance with the accepted request. In a case where it is determined that the orientation of the print target image is to be changed, control is performed so as not to execute the binding processing.

If a print job is designated to interrupt print, processing of any print job currently being processed is interrupted, print processing of the instructed print job is immediately performed and resumption of the interrupted print job is automatically performed afterward. Further, if an interrupt print occurs, the sending source of the interrupted print jobs (host computers, etc.) are notified that an interrupt occurred.

Print control apparatus, print control method, memory medium for storing print control program, and print control program

In order to maintain stackability while taking printing conditions into consideration, a control method for controlling a printing system for a stacking unit stacking a sheet printed by a printing unit, includes: determining whether or not a predetermined number of sheets on which the same printed data is printed by the printing unit are stacked continuously by the stacking unit; and controlling, in a case where a predetermined number of the sheets on which the same printed data is printed are determined by the determining unit to be continuously stacked by the stacking unit, the stacking unit so as to not continuously stack more of the sheets on which the same printed data is printed than the predetermined number of sheets.

Printing system, control method thereof, and printing apparatus

When a print job described in JL (job language) is transferred from a host device via a communication medium, JL is interpreted by a JL parser, encapsulated PDL (page description language) is interpreted by a PDL translator, and image data to be printed is produced, and printed in a printer engine. When printing is completed, information on the paper output place is stored in a job information table. When an inquiry in JL is made from the host, on the basis of this, the job information table is retrieved, and answer data on the corresponding paper output place is returned to the host device, and informed to a user via display processing on the host device or the like.

Printing system, method for controlling printing system, and computer-readable memory medium

A print job can be identified without the print data of the print job being analyzed, and print data for a print job that is selected, e.g., print data stored in an input buffer, can be invalidated. In addition, the cancellation of a print job can be designated in real time. To achieve the above object, a host computer and a printer are interconnected via a communication medium. The host computer comprises job packet generation means for adding a header to print data to form a packet for each print job that is generated. The printer comprises job detection and registration means for detecting the start and end of a print job in accordance with the contents of the header of a packet received from the host computer, and for registering the print job in a database.
