Timer device for a digital printer and method of printing

摘要

A digital printer has a printhead (10) for printing on a substrate and an encoder (14) which emits pulses (122) to indicate the relative distance moved by the printhead. A timer device for the digital printer emits output print pulses (151) for effecting printing and a count module (130) for receiving pulses (122) from the encoder (14) and emitting a print signal after a predetermined number of encoder pulses (122) to effect the emission of the output print pulse. The timer device is adapted to add a delay between the emission of the print signal and the emission of the output print pulse (151). In examples described, the pitch of the printed droplets can be closely controlled.
