In ink jet printers employing raster printing with a continuously movin printhead, and the raster picture elements (pels) are printed in sequence rather than simultaneously, if the printer is arranged as a bidirectional printer, there is an offset of one raster width between the left to right print line and right to left print line. This results in uneven margins detracting from the overall print quality which is achievable by the Sweet type of continuous-stream ink jet printer.
