Patent ID: 7918618

Claim:
A printer assembly for printing on a supply of media traveling in a media direction, said printer assembly comprising: a platen assembly comprising a platen that is configured to rotate on a platen axis and further configured to support the media; a print head assembly comprising a print line configured to print on the media as the media passes between the print line and the platen assembly wherein the print head assembly is elongated and has a pair of opposite ends; at least one biasing device configured to bias the print head assembly against the media supported by the platen assembly; an angulation arm that is elongated and defines two ends; and a pair of pivot members extending from the angulation arm proximate respective ends of the angulation arm and adjacent a respective one of the opposite ends of the print head assembly, wherein the pair of pivot members are pivotally supported by a surface that is fixed relative to the platen axis, wherein the angulation arm is coupled to the print head assembly such that the print head assembly pivots about the pair of pivot members and tilts in the media direction as the media travels between the print head assembly and the platen assembly so as to adjust to variations of the media, and wherein the angulation arm is uncoupled to the print head assembly with respect to pivoting of the print head assembly in a direction transverse to the media direction.
