Printing system, printing apparatus, and printing control method

A printing apparatus comprising:

• a print head in which a plurality of printing elements are arrayed;
• a conveying unit configured to convey a print medium to a print area facing the print head in a conveying direction intersecting with an array direction of the printing elements;
• a control unit configured to set a conveying speed of the conveying unit;
• an array direction adjustment unit configured to adjust a print position of the print head in the array direction based on an array direction adjustment value;
• an inclination adjustment unit configured to adjust an inclination of a print position of the print head with respect to the conveying direction and configured to divide the array of the printing elements into a plurality of blocks at at least one division position provided with a predetermined interval based on an inclination adjustment value and shift image data in the conveying direction in each of the blocks;
• and
• a division position change unit configured to change the division position to a position shifted by an amount corresponding to the array direction adjustment value in a direction opposite to a direction of adjustment by the array direction adjustment unit in the array direction.

A control method of a printing apparatus configured to use a print head in which a plurality of printing elements are arrayed to convey a print medium in a direction intersecting with an array direction of the printing elements and to print an image, the control method comprising:

• an image data creation step of creating image data used for printing by the printing apparatus;
• an array direction adjustment step of adjusting a print position of the print head in the array direction based on an array direction adjustment value;
• an inclination adjustment step of adjusting an inclination of a print position of the print head with respect to the conveying direction based on an inclination adjustment value;
• a division step of dividing the array of the printing elements into a plurality of blocks and shifting a position of the division by an amount corresponding to the array direction adjustment value in a direction opposite to a direction of adjustment in the array direction adjustment step in the array direction;
• an acquisition step of acquiring a maximum concurrent drive number in the printing elements, regardless of the array direction adjustment value and the inclination adjustment value, based on the image data and a plurality of predetermined inclination adjustment values selected from a predetermined range;
• and
• a setting step of setting a conveying speed of the print medium based on the maximum concurrent drive number.
