Abstract: A carriage control system provides programmed selection between values of line pitch at which a printer is to operate. Selection of one or the other of two values of line pitch is made by detecting the presence or absence of a flag bit in the first address position of a carriage control buffer used to store coded representations of channel skip commands which determine the skip operations of the printer carriage.
