Abstract
Plural successive light beam pulses are directed through a continuously adjustable aperture. An actuator is driven to change an aperture diameter of the continuously adjustable aperture for each of the plural successive light beam pulses directed therethrough. The aperture diameter is adjusted in this manner in accordance with a pixel diameter of each of respective plural pixels to be printed on a print medium by the plural successive light beam pulses.
