Abstract
A method and system for ink jet printing of characters in a variable rate document transport creates a correct column pitch for the document speed. An endorser control system includes a processor having a DMA unit for retrieving column data at a column data rate wherein the processor controls the variable document travel rate. The system further includes a sequencer for converting the column data into dot data. The DMA unit in conjunction with a compare match timer writes the column data from the processor memory to the sequencer at the specified column data rate.
