Abstract
The invention provides methods, systems, and drivers for controlling an inkjet printing system. The driver may include logic including a processor, memory coupled to the logic, and a fire pulse generator circuit coupled to the logic. The fire pulse generator may include a connector to facilitate coupling the driver to a print head. The fire pulse generator circuit may also include a fixed current source circuit adapted to generate a fire pulse with a constant slew rate that facilitates easy adjustment of ink drop size. The logic is adapted to receive an image and to convert the image to an image data file. The image data file is adapted to be used by the driver to trigger the print head to deposit ink into pixel wells on a substrate as the substrate is moved in a print direction. Numerous other aspects are disclosed.
