Abstract

Printing processing is performed on a sheet having a characteristic value within a range of a characteristic value of a sheet which is defined usable in the printing processing in accordance with a specific print job. Specifically, in a case where a test page print job is input, a CPU selects a sheet feeding tray on which sheets having a characteristic value within a range of a characteristic value represented by characteristic value range information. The CPU performs a control operation so that a sheet is fed from the selected sheet feeding tray to a printer unit and the printer unit executes the test page print job.

Claims

1. A printing apparatus comprising:

a plurality of sheet stacking units including at least a first sheet stacking unit and a second sheet stacking unit;

an input unit configured to input a print job to which first characteristic value information representing a range of characteristic values of a sheet to be used for the print job is set;

a storage unit configured to store, for at least the first sheet stacking unit and the second sheet stacking unit, second characteristic value information representing a characteristic value of a sheet stacked in a sheet stacking unit;

a selection unit configured to select, when the print job is inputted, a sheet stacking unit having stacked a sheet within the range of the characteristic values represented by the first characteristic value information, from among the plurality of sheet stacking units, based on the second characteristic value information stored in the storage unit;

a feeding unit configured to feed the sheet form the sheet stacking unit selected by the selection unit; and

a printing unit configured to perform print processing of the print job using the sheet fed by the feeding unit,

wherein the feeding unit does not feed a sheet in a case where there is no sheet stacking unit having stacked a sheet within the range of the characteristic values represented by the first characteristic value information, among the plurality of sheet stacking units.

2. The printing apparatus according to claim 1,

wherein the characteristic value of the sheets represents a weight per unit area of one of the sheets.

3. The printing apparatus according to claim 1, further comprising a display unit configured to display the first characteristic value information, when the selection unit does not select the sheet stacking unit having stacked the sheet within the range of the characteristic values represented by the first characteristic value information.

4. A non-transitory computer-readable medium having stored thereon a computer program comprising program code having computer-executable instructions for causing a computer to execute the control method of claim 1.

5. The printing apparatus according to claim 1, wherein the print job is a calibration job.

6. The printing apparatus according to claim 1, wherein the print job is a test page printing job.

7. The printing apparatus according to claim 1, wherein the selection unit selects a sheet stacking unit based on a predetermined priority order, in a case where there is more than one sheet stacking unit having stacked a sheet within the range of the characteristic values represented by the first characteristic value information.

8. A control method for controlling a printing apparatus, comprising:

inputting a print job to which first characteristic value information representing a range of characteristic values of a sheet to be used for the print job is set;

storing, for at least a first sheet stacking unit and a second sheet stacking unit of a plurality of sheet stacking units, second characteristic value information representing a characteristic value of a sheet stacked in a sheet stacking unit;

selecting, when the print job is inputted, a sheet stacking unit having stacked a sheet within the range of the characteristic values represented by the first characteristic value information, from among the plurality of sheet stacking units, based on the second characteristic value information stored by the storing;

feeding the sheet from the sheet stacking unit selected by the selecting; and

printing the print processing of the print job using the sheet fed by the feeding,

wherein the feeding does not feed a sheet in a case where there is no sheet stacking unit having stacked a sheet within the range of the characteristic values represented by the first characteristic value information, among the plurality of sheet stacking units.

9. The control method according to claim 8, further comprising displaying the first characteristic value information, when the selecting does not select the sheet stacking unit having stacked the sheet within the range of the characteristic values represented by the first characteristic value information.

10. The control method according to claim 8,

wherein the characteristic value of the sheets represents a weight per unit area of one of the sheets.
