Abstract
An ink jet printer deposits ink drops from a plurality of jet drop streams along a plurality of parallel adjacent print lines on a sheet of paper. The printer includes a sheet supporting drum, means for rotating the drum, and a print head which is slidably mounted adjacent the drum for linear movement in a direction parallel to the axis of rotation of the drum. A rotatable cam defines a continuous endless camming surface with the cam being driven by a drive arrangement interconnected with the means for rotating the drum. A cam follower means follows the continuous camming surface and moves the print head in a direction parallel to the axis of rotation of the paper supporting drum such that jet streams are directed to deposit drops along respective ones of the print lines during successive rotations of the drum.
