Image printing apparatus and control method therefor

A method of controlling an image printing apparatus which prints an image while scanning a carriage holding a printing head on a printing medium in a main scanning direction at a predetermined speed, comprising:

• a detection step of detecting interruption of image printing during the image printing by one scanning;
• and
• a control step of, when the interruption is detected, controlling to cause the carriage to stand by at a position returned by a predetermined distance from an interruption position toward a printing start position, and when a cause of the interruption is eliminated, controlling to move the carriage from the position returned by the predetermined distance to the interruption position and start the image printing,
• wherein in the control step, the carriage is moved at a speed higher than the predetermined speed in at least movement of the carriage from the interruption position to the position returned by the predetermined distance and at least part of movement of the carriage from the position returned by the predetermined distance to the interruption position.

A control program of controlling an image printing apparatus which prints an image while scanning a carriage holding a printing head on a printing medium in a main scanning direction at a predetermined speed, comprising:

• a program code for a detection step of detecting interruption of image printing during the image printing by one scanning;
• and
• a program code for a control step of, when the interruption is detected, controlling to cause the carriage to stand by at a position returned by a predetermined distance from an interruption position toward a printing start position, and when a cause of the interruption is eliminated, controlling to move the carriage from the position returned by the predetermined distance to the interruption position and start the image printing,
• wherein in the control step, the carriage is moved at a speed higher than the predetermined speed in at least movement of the carriage from the interruption position to the position returned by the predetermined distance and at least part of movement of the carriage from the position returned by the predetermined distance to the interruption position.

A computer-readable storage medium which stores a control program of controlling an image printing apparatus which prints an image while scanning a carriage holding a printing head on a printing medium in a main scanning direction at a predetermined speed, the control program comprising:

• a program code for a detection step of detecting interruption of image printing during the image printing by one scanning;
• and
• a program code for a control step of, when the interruption is detected, controlling to cause the carriage to stand by at a position returned by a predetermined distance from an interruption position toward a printing start position, and when a cause of the interruption is eliminated, controlling to move the carriage from the position returned by the predetermined distance to the interruption position and start the image printing,
• wherein in the control step, the carriage is moved at a speed higher than the predetermined speed in at least movement of the carriage from the interruption position to the position returned by the predetermined distance and at least part of movement of the carriage from the position returned by the predetermined distance to the interruption position.
