A print control apparatus may include a determination unit and a print control unit. The print control apparatus causes a printing unit to perform duplex printing on a continuous sheet and the determination unit determines whether a continuous sheet usable by a first print job is the same as a continuous sheet usable by a second print job. If the determination unit determines that the two continuous sheets are the same, the print control unit perform controls to, cause the printing unit to continuously print images of the first print job to be arranged on a first surface of the continuous sheet and images of the second print job to be arranged on the first surface and thereafter cause the printing unit to print images of the first print job and the second print job to be arranged on an opposite surface of the continuous sheet.

Print control apparatus and method for duplex printing on a continuous sheet

An apparatus includes a presenting unit and a control unit. The presenting unit presents a plurality of options for interrupt printing along with an amount of incompletely printed sheet to be discharged while images are being printed on both surfaces of a continuous sheet in accordance with a prior job. The control unit interrupts, when one of the plurality of options presented by the presenting unit is designated, the prior job in timing according to the designated option to execute an interrupt job.

Apparatus, method and program

A printing apparatus sequentially prints a plurality of images on a first surface of a sheet, and then sequentially prints a plurality of images on a second surface that is a back surface of the first surface. When a state of a printing unit is determined not to be normal when printing on the first surface, the printing apparatus executes processing for maintenance by using a sheet different from the sheet used for printing on the first surface.

Printing method and printing apparatus for printing maintenance images on a continuous sheet using a duplex printer

An apparatus includes an input unit and a printing control unit to cause a printing unit to execute printing on a continuous sheet. The input unit inputs an instruction for printing by the printing unit. The printing control unit causes the printing unit to execute printing according to a second job subsequent to printing on a first surface of the continuous sheet based on a first job, wherein the instruction input by the input unit may include a first job that is a two-sided printing and a second job that is a one-sided printing, or a first job that is a one-sided printing and a second job that is a two-sided printing. A supplying unit is controlled to supply the printed continuous sheet to a reversal unit which reverses the continuous sheet to execute printing on a second surface after executing printing on a first surface of the continuous sheet.

Apparatus capable of executing printing on both surfaces of a continuous sheet and printing control method for executing printing on both surfaces of a continuous sheet

An apparatus for printing job data, includes a rendering unit configured to rasterize the job data into bitmap data, a print engine unit configured to print the rasterized job data, and a control unit configured to transmit the job data to the rendering unit, to receive the rasterized job data, to transmit the rasterized job data to the print engine unit. The control unit switches between saving the rasterized job data in a spool space and inspecting the job data without saving the job data to the spool space, depending on free space situation of the spool space.

Inspecting for errors in print data and conditionally saving the print data dependent upon memory space

Printing method and printing apparatus for printing a plurality of images on a sheet using a print head

A state of a print head is checked by printing a plurality of images in order on a sheet fed from a sheet feeding unit, and reading the printed images. A region that is inappropriate for performing printing on the fed sheet is detected. When the inappropriate region has been detected, printing the images is stopped and the sheet is cut. Of the cut sheets, the sheet at an upstream is sent back to the sheet feeding unit. Subsequently, the sheet is again fed to perform printing and conduct a test.

A print control apparatus configured to cause a printing unit to perform print processing includes a determination unit configured to determine whether a condition for executing maintenance processing of the printing unit is satisfied, a shortening unit configured to shorten redundant maintenance operations in first maintenance processing and second maintenance processing in a case where the determination unit determines that a condition for executing the second maintenance processing is satisfied before completion of the first maintenance processing, and a control unit configured to cause the first maintenance processing and the second maintenance processing to be carried out after the shortening unit shortens the redundant maintenance operations.

Print control apparatus, print control method, and recording medium

A printing control apparatus may execute printing on a continuous sheet by using a printing unit. The printing control apparatus includes a reversal unit, an input unit, and a printing control unit. In executing printing by the printing unit on both surfaces of the continuous sheet, the reversal unit reverses the continuous sheet to execute printing on a second surface after executing printing on a first surface. If the printing on the first surface currently is being executed by the printing unit to execute two-sided printing of a preceding job based on a preceding job in a case where an instruction for interruption printing is input by the input unit, the printing control unit executes the interruption printing according to the instruction subsequent to the printing on the first surface of the continuous sheet based on the preceding job, and supplies the printed continuous sheet to the reversal unit.
