Abstract
A method and apparatus for controlling a printer of the type having plural print heads, each being selectively energizable to print an indicium whose relative intensity is determined by the duration of energization of that printer. Data representing the intensity of the indicia to be printed by each of the print heads is received and stored. Respective ones of the print heads are selectively energized over time durations determined by the data. The number of print heads which are energized is detected, and the duration that the respective print heads are energized is varied as a function of the number of print heads which are concurrently energized.
