A printer including a plurality of print drums and capable of producing, e.g., color printings is disclosed. When a closed position sensor responsive to a door outputs a close signal and when a drum sensor assigned to a print drum to be mounted outputs an absence signal, a controller controls drum drive sections such that a mount/dismount drive section assigned to the print drum to be mounted takes the position corresponding to a mount position. Also, in response to a mount position signal output from a mount position sensor, the controller controls the drum driving device such that the mount/dismount drive section stops at the position corresponding to the mount position. The printer allows an operator thereof to mount the print drums without pressing, e.g., mount/dismount keys each time and thereby saves time.
