Abstract: In printing data of a plurality of pages on a continuous sheet, it is determined whether the data is to be printed on a single side of the continuous sheet or on both sides thereof. A first sequence of pages arranged on a first side of the continuous sheet occurring when it is determined that the data is to be printed on the single side and a second sequence of pages arranged on the first side of the continuous sheet occurring when it is determined that the data is to be printed on the both sides such that the first and second sequences are opposite to each other. Each of the first and second sequences indicates whether the pages are arranged in descending order or in ascending order.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In order to prevent a printing process from clogging by reason of being incapable of discharging a sheet to a discharge destination in the case of duplex printing on a continuous sheet, the number of pages to be printed continuously on the same side of the sheet is decided so that the number of required discharging destinations conforms to the number of available discharge destinations. Then, according to the decision, printing on the same side of the sheet is performed, and the sheet is discharged to the respective discharge destinations.

Abstract: In printing data of a plurality of pages on a continuous sheet, it is determined whether the data is to be printed on a single side of the continuous sheet or on both sides thereof. A first sequence of pages arranged on a first side of the continuous sheet occurring when it is determined that the data is to be printed on the single side and a second sequence of pages arranged on the first side of the continuous sheet occurring when it is determined that the data is to be printed on the both sides such that the first and second sequences are opposite to each other. Each of the first and second sequences indicates whether the pages are arranged in descending order or in ascending order.

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.

Abstract: 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.

Abstract: A print system in which when a print driver can previously confirm data structure information during data generation, printing efficiency can be raised by using the structure information is provided. While the printer driver which is made operative by a host computer is generating print data, if the structure information of the print data can be confirmed, prior to sending the print data, structure information of the data is sent to a printer. For example, when the printer is notified of structure information showing that color/monochrome data continues for a predetermined number of rasters in the first block of the print data by a host computer, the printer selects the optimum printing method on the basis of the structure information without analyzing the print data.

Abstract: A printer includes a receiver for receiving a first command and a second command from an external apparatus, and an execution device for executing the first command when the receiver receives the first command, and for executing the second command in preference to the first command when the receiver receives the first command and then receives the second command.
