ABSTRACT:
A method for generating a stroke frequency signal on a plurality of ink jet printheads arranged along a moving web includes the steps of: (a) coupling the raster printer controller to the plurality of printheads with a plurality of data links in a daisy-chain configuration, where the printer controller is at the beginning of the daisy-chain; (b) embedding a web velocity signal indicative of web velocity in data, by the printer controller; (c) communicating the data with the embedded velocity signal to each of the printheads by transmitting the data with the embedded velocity signal onto the daisy-chain; (d) each of the printheads deriving the web velocity signal from the data received from the daisy-chain by each of the printheads; and (e) generating a stroke frequency signal from the web velocity signal by each of the printheads. Preferably, the generating step includes the steps of (f) clocking a counter with a clock signal, where the counter has a terminal count output; (g) calculating a preload value from the velocity signal; and (h) initializing the counter with the preload value; where the terminal count output of the counter will be the stroke frequency signal.
