摘要： The disclosure discloses a printer includes a controller. The controller performs a first feed control process, a temperature-difference calculation process, and a first printing speed determination process. In the first feed control process, in a state where an energizing device does not perform energization to the heating element, the driving device is controlled to perform non-energization feeding while causing a thermal head to contact a print-receiving medium. In the temperature-difference calculation process, during execution of the non-energization feeding, a first deviation between two of the head temperatures which are respectively detected by the first temperature detecting device at different timings is calculated. In the first printing speed determination process, the printing speed is determined on the basis of the first deviation.

摘要： A carriage moving device has a motor, and a carriage. The carriage moves in a first direction when the motor rotates forwardly, while the carriage moves in a second direction which is opposite to the first direction when the motor rotates reversely. The carriage moving device further includes a facing object having a plurality of reflection ratios at a plurality of positions in the scanning direction. A first sensor unit has a light emitting unit configured to emit light to the facing object and a light receiving unit configured to receive light reflected by the facing object. A second sensor unit is configured to output a second signal in response to movement of the carriage. The controller notifies an error of the second sensor unit in response to a condition where a changing amount of the first signal in the reversing step exceeds a threshold amount and the controller cannot obtain the second signal.

摘要： There is provided a printing apparatus that can perform print timing control while moving a print head with high precision even when variation in moving speed of the print head is relatively large. More specifically, a prediction speed is obtained based on a detected moving speed of the print head and a control target speed at the time of detection, and then a print timing of the print head is controlled based on the prediction speed. Accordingly, a correction speed of the print timing is considered to be the obtained prediction speed. This makes it possible to minimize a landing error even when a speed variation is large.
