Abstract
A plain paper facsimile receiver using a reciprocating shuttle, and, preferably, an ink jet printhead having one or more columns of ink jet nozzles. The printhead is mounted on the shuttle carriage at an angle so as to result in a line density of twice the line density specified in the facsimile standard used. In a first embodiment, the control circuitry is arranged so that dots formed by any nozzle can be formed only in alternate dot columns of the printed image, and dots formed by adjacent nozzles cannot be formed in the same dot column. In a second embodiment, a denser image is formed by printing an even number of dots in each pel corresponding to a picture element of the original facsimile image.
