Abstract
A compact plotter is disclosed, having a small area in which a plurality of print heads (10) are laterally scanned to print impressions on the paper (14), and the paper (14) is incrementally advanced by an indexer (42) past the print heads (10). A paper travel encoder (36) measures the paper advancement. A computer 22 and a processor 26 are provided to coordinate the printing of pattern data stored in a data base (24) both with the movement of the print heads (10) and the advancement of the paper (14). The computer (22) allocates data from the data base (24) to be printed according to the amount of paper advancement. If the paper (14) is advanced more than a predefined amount, more data is allocated for printing than is actually printed. If the paper (14) is advanced less than the predefined amount, less data is allocated to be printed than is actually printed.
