<p>Printing apparatus for use with a document transport mechanism, includes front and rear printers (12-1,12-2) which are identical in construction with each having a compact housing (60) in which an ink jet print head (82) is mounted. The housing (60) has first and second side walls (52,54), a front wall (56) which also functions as a guide for guiding documents (14) to be printed upon therepast, and a rear wall which supports a circuit board (59) which houses driver electronics for the associated printer (e.g. 12-1). The print head is mounted on a carriage (80) which is moved within the housing (60) in a first direction which is perpendicular to the direction in which the documents (14) are moved in a document track (18) past the printers. The front and rear printers (12-1,12-2) are detachably mounted on opposed sides of the document track (18) to enable the printing of alphanumerics or graphics on the front or the rear of a document (14) moving therepast. <IMAGE></p> |
