A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

The present invention relates to printing apparatuses to perform printing on sheet-shaped print media that are conveyed and methods of controlling the printing apparatuses, and storage media storing programs for controlling the printing apparatuses.
Japanese Patent Laid-Open No. 2002-278186 discloses techniques in which the conveyance speeds on the upstream side and on the downstream side of the image forming portion are different from the conveyance speed at the image forming portion. For example, in a technique disclosed in Japanese Patent Laid-Open No. 2002-278186, the conveyance speed of the print medium after printing is increased when there is no succeeding print medium, to shorten the retention time of the print medium within the conveying path, and thus to improve the throughput. When there is a succeeding print medium, the print medium after printing is conveyed at a constant conveyance speed with no change to make favorable the stacking performance of the print medium at the discharge position.
Meanwhile, since the inkjet printing apparatus performs printing by applying ink to the print media, the applied ink penetrates the print medium. Thus, depending on the amount of ink applied, changes in the physical properties of the print medium occur, such as the decrease in the rigidity and the increase in the friction coefficient. If the technique in Japanese Patent Laid-Open No. 2002-278186 is applied to such inkjet printing apparatuses, when a print medium with changed physical properties is conveyed and discharged at the same conveyance speed as the one at the image forming portion, the print medium may buckle at the discharge position. This may cause jamming at the discharge position when printing is performed continuously on print media.
FIG. 1 is a view of a printing apparatus in a standby state;
FIG. 2 is a diagram of a control configuration of the printing apparatus;
FIG. 3 is a view of the printing apparatus in a print state;
Hereinafter, with reference to the attached drawings, description will be provided in detail for examples of printing apparatuses, methods of controlling a printing apparatus, and a storage medium, according to the present invention.
With reference to FIGS. 1 to 10, description will be provided for a first embodiment of a printing apparatus according to the present invention. FIG. 1 is an internal configuration diagram of an inkjet printing apparatus 1 (hereinafter “printing apparatus 1”) used in the present embodiment. In the drawings, an x-direction is a horizontal direction, a y-direction (a direction perpendicular to paper) is a direction in which ejection openings are arrayed in a print head 8 described later, and a z-direction is a vertical direction.
The printing apparatus 1 is a multifunction printer comprising a print unit 2 and a scanner unit 3. The printing apparatus 1 can use the print unit 2 and the scanner unit 3 separately or in synchronization to perform various processes related to print operation and scan operation. The scanner unit 3 comprises an automatic document feeder (ADF) and a flatbed scanner (FBS) and is capable of scanning a document automatically fed by the ADF as well as scanning a document placed by a user on a document plate of the FBS. The present embodiment is directed to the multifunction printer comprising both the print unit 2 and the scanner unit 3, but the scanner unit 3 may be omitted. FIG. 1 shows the printing apparatus 1 in a standby state in which neither print operation nor scan operation is performed.
