ABSTRACT:
A laser-actuatable inkjet printing system for printing an image from digital raster data onto a print medium is disclosed. The printing system includes at least a printhead having a laser-penetrable chamber for holding ink therein. The printhead also includes a plurality of nozzles defined through a wall of the printhead to connect to the chamber. The printing system further includes a laser for producing a laser beam that is scanned across the chamber for selectively expelling droplets of ink. The expulsion of ink is in accordance with the digital raster data. Ink is expelled through multiple adjacent nozzles simultaneously onto the print medium to form each pixel of the image.
