ABSTRACT:
Ink jet print quality is improved and higher pen speed permitted by a bidirectional printing protocol. According to the new protocol, each individual character to be printed is first partitioned into a leading portion and a trailing portion. The trailing portion includes all trailing edge bits. Only the leading portion is printed on a forward pass of the ink jet pen. The trailing portion is printed on a reverse pass of the pen, so that trailing edge ink drops are instead printed as leading edge ink drops. As a result, satellite ink drops are directed toward the center of the character, where they are covered by primary ink drops, thereby minimizing character edge roughness associated with exposed satellite ink drops.
