In an inkjet printer, a controller is configured to calculate, during movement of a carriage in a scanning direction, a signal level difference between a first detection signal in a mountain peak zone including an assumed mountain peak position and the first detection signal in a valley bottom zone including an assumed valley bottom position identified, based on information stored in a storage, and alternately execute, during the movement of the carriage, an ejection process of ejecting ink drops, and a conveying process of conveying the sheet by a predetermined line feed width. In the printing process, the printing head and the conveyor are driven according to a first condition when the signal level difference is equal to or larger than a threshold value, while driven according to a second condition when the signal level difference is less than the threshold value.

For a printing apparatus, a first conveyance speed for a first printing medium is determined according to first print data to be printed on the first printing medium and a second conveyance speed for a second printing medium is determined according to second print data to be printed on the second printing medium that follows the first printing medium along a conveying path. In a case where the second conveyance speed is equal to the first conveyance speed, a conveyance operation of the second printing medium is started before the first printing medium is discharged from the conveying path. In a case where the second conveyance speed is different from the first conveyance speed, the conveyance operation of the second printing medium is started after the first printing medium is discharged from the conveying path.
