A printer capable of printing a multicolor image with a single pass of a paper or similar recording medium includes a plurality of print drums. Drum drive gears each are mounted on a particular print drum such that the print drum is replaceable. The print drums are interlocked to each other by rotatable members including relay gears meshing with the drum drive gears, timing pulleys fixed to the relay gears, a timing belt, and pulleys for adjustment. Each rotatable member has teeth the number of which is selected such that the number of rotations of the rotatable member to occur in a single period of the print drums is an integral multiple of the number of rotations of the print drums.
