A detecting element detects a rotation state of the rotary member during rotation. A control unit generates a one-rotation current profile, representing the magnitude pattern of current corrected on the basis of the detected rotation state, corresponding to one rotation of the rotary member, and supplies corrected current to rotate the rotary member. When the length of the medium in the rotation direction, the length of the medium in the axial direction, or the type of the medium is changed, the control unit generates the one-rotation current profile before starting printing, and repeatedly supplies the corrected current to the motor to print the image. | 2009-07-23 |
20090184989 | CONTROLLER - A controller arranged to provide print data to a print apparatus, said print data comprising an image to be printed on a disc, said image being such that at least one print parameter is determinable from said image when printed on said disc; receive said at least one print parameter; and control a subsequent printing operation on a disc based on said received at least one print parameter. | 2009-07-23 |
