Abstract
An image recording apparatus with inexpensive data line resequencing circuitry for formatting image signals to a print head. The circuitry includes a resequencing line store device connectable to a data link and a control link for resequencing at least one first line of sequentially ordered data bits carried by the data link according to control signals carried by the control link. The resequencing line store device includes a plurality of interconnected memory cells operable for storage and selectable transfer of the data bits in response to the control signals, whereby the plurality of cells are arranged in a plurality of cell groups and a plurality of cell subgroups corresponding respectively to groups and subgroups of the bits. The bits may be shifted into the plurality of groups in sequential order and shifted from the plurality of cell subgroups in a non-sequential order corresponding to the first and second partitions.
