Abstract
Carriage and paper motion overlap method and apparatus are described. The preferred method utilizes carriage ramp-down and unidirectional, constant-speed periods of time to advance paper via the printer's paper advancement mechanism while avoiding current-intensive ramp-up periods of time during which demands on the printer's power supply are high. The printer's controller is programmed to implement preferably concurrently operable processes one of which controls paper movement and the other of which controls carriage movement. The processes signal one another based upon their monitoring of defined conditions of the printer and the print buffer, and by setting and clearing a flag.
