Abstract
In a matrix printer, the knife blade (27) of the cutting device for the imprinted paper is integral with a cam carrier of a planar sliding cam drive roller (3) supported on the matrix printing head (1). Three cam sections (41, 42, 43) on the cam carrier are contacted by the drive roller (3) as it moves back and forth with the matrix printing head (1) during printing, and the drive roller contacting one of the cam sections (42) to move the knife blade laterally of the imprinted paper to cut it as it leaves the printing site, and contacting another of the cam sections (43) to return the knife blade to its retracted position.
