ABSTRACT:
A system remaps image data generated by successive sweeps of the image by a single transducer element into a format for use by a print head assembly which requires the simultaneous application of plural modulating signals to a plurality of print elements thereon to effect printing of the image. Horizontal strips of the image data corresponding to the height of the arrangement of print elements within the head assembly are successively transferred from a page buffer which stores the image to a horizontal strip buffer, from which successive columns of each strip along the length thereof are transferred through a rotator for rearrangement into new groups of data oriented at right angles relative to the prior arrangement thereof for storage in a vertical strip buffer. From the vertical strip buffer the new groups of data are applied through deserializers to modulate the plural print elements in the form of ink jet nozzles as the head assembly undergoes successive sweeps across a printable medium.
