Abstract: A motor control device includes a motor driver and a control unit. The motor driver supplies a drive current to a stepping motor. The control unit is configured to control the motor driver to start a supply of the drive current to the stepping motor in response to a start instruction, and increase the drive current to the stepping motor from zero to a predetermined current value stepwise over a predetermined time period.

Abstract: A printer includes a print head configured to print along a raster direction portions of an image in units of a raster, a movement mechanism that includes a stepping motor and is configured to move one of the printing medium and the print head so as to change a relative position between the printing medium and the print head in a direction intersecting the raster direction, and a control unit configured to control the print head and the movement mechanism. The print head is controlled to perform printing of one raster each time the relative position between the printing medium and the print head is changed by an interval of the raster. The movement mechanism is controlled to make a drive interval of the stepping motor at least one time step longer than a preceding drive interval before a rotation speed of the stepping motor reaches a predetermined target speed.
