Abstract
A printing apparatus performs print processing on a plurality of sheets according to print data input by an input unit, and sets the printing unit to a first operation state in which monochromatic print processing is capable of being performed or to a second operation state in which color print processing is capable of being performed. The printing apparatus enables selection between a first print mode and a second print mode. In the first print mode, a sheet is conveyed at a defined speed in the monochromatic print processing and is conveyed at a speed lower than the defined speed in the color print processing. In the second print mode, a sheet is conveyed at a speed lower than the defined speed both in the monochromatic print processing and in the color print processing.
Claims13
A printing apparatus comprising:
- a printing unit configured to perform print processing on a sheet based on image data;
- a selection unit configured to select between a first print mode and a second print mode, the first print mode being for conveying a sheet at a first speed and performing monochromatic print processing for all pages, and the second print mode being for conveying a sheet at a second speed lower than the first speed regardless of whether each page included in the image data is monochromatic image data or color image data and performing monochromatic print processing for a page of the monochromatic image data and performing color print processing for a page of the color image data;
- and
- a control unit configured to control the printing unit to perform print processing in the print mode selected by the selection unit.
A printing apparatus comprising:
- a printing unit configured to perform print processing on a sheet based on image data;
- a selection unit configured to select between a first print mode and a second print mode, the first print mode being for, in a case where a first page to a (N−1)th page included in the image data are monochromatic image data and a Nth page is color image data, conveying the sheet at a first speed when printing for the first page to the (N−1)th page is performed, conveying the sheet at a second speed lower than the first speed when printing for the Nth page is performed, and conveying the sheet at the second speed when printing for a (N+1)th page to the end page is performed regardless of whether the page to be printed is the monochromatic image data or the color image data, and the second print mode being for conveying, for each page, the sheet at the second speed regardless of whether the page to be printed is the monochromatic image data or the color image data;
- a speed changing unit configured to, in a case where the first print mode is selected by the selection unit, change a conveying speed of the sheet from the first speed to the second speed when printing of the Nth page is performed;
- and
- a control unit configured to control the printing unit to perform print processing in the print mode selected by the selection unit.
A control method for a printing apparatus comprising a printing unit configured to perform print processing on a sheet based on image data, the method comprising:
- selecting between a first print mode and a second print mode, the first print mode being for conveying a sheet at a first speed and performing monochromatic print processing for all pages, and the second print mode being for conveying a sheet at a second speed lower than the first speed regardless of whether each page included in the image data is monochromatic image data or color image data and performing monochromatic print processing for a page of the monochromatic image data and performing color print processing for a page of the color image data;
- and
- controlling the printing unit to perform print processing in the selected print mode.
A control method for a printing apparatus comprising a printing unit configured to perform print processing on a sheet based on image data, the method comprising:
- selecting between a first print mode and a second print mode, the first print mode being for, in a case where a first page to a (N−1)th page included in the image data are monochromatic image data and a Nth page is color image data, conveying the sheet at a first speed when printing for the first page to the (N−1)th page is performed, conveying the sheet at a second speed lower than the first speed when printing for the Nth page is performed, and conveying the sheet at the second speed when printing for a (N+1)th page to the end page is performed regardless of whether the page to be printed is the monochromatic image data or the color image data, and the second print mode being for conveying, for each page, the sheet at the second speed regardless of whether the page to be printed is the monochromatic image data or the color image data;
- changing, in a case where the first print mode is selected, a conveying speed of the sheet from the first speed to the second speed when printing of the Nth page is performed;
- and
- controlling the printing unit to perform print processing in the selected print mode.
