Abstract
The present invention is directed to systems and methods for formatting hardware for a printhead, for use in a printing device. The systems and methods of the present invention can support the formatting function with hardware formatting logic. This hardware formatting logic can support multiple printhead platforms. The hardware formatting logic of the present invention can perform bit shifting, resolution reduction, bit per pixel reduction, data masking for shingling, and input data sourcing. The present invention can also include a system processor further including an embedded ARM processor which can fetch and execute instructions and/or firmware. These instructions can direct the embedded processor to configure a format block included within the system processor. The format block can be configured by the system processor via one or more control registers.
