A printing system includes a controller and a thermal printing head including multiple driving elements and an integrated transmission control interface. The thermal printing head is coupled to the controller. The driving elements are configured to print. The integrated transmission control interface coupled to the controller and driving elements is configured to receive from the controller at least one of a compensation data, a printing data, a clock signal, a data signal, a latch signal or a start-heating signal, and send to driving elements the at least one of the compensation data, the printing data, the clock signal, the data signal, the latch signal or the start-heating signal.

Printing system

Imaging offset problems in imaging systems, such as electrophotographic (EPG) printers and copiers, are overcome. Imaging offset results from misaligned exposure units that, when uncompensated, produce dots on a photoreceptor belt at exposure positions that are offset from ideal dot positions. An imaging-offset compensating method of the invention first determines the imaging offset, which is a distance that may include a magnitude and a direction. The imaging offset is determined with respect to the ideal dot position. A time factor is then determined based on the magnitude of the imaging offset for each exposure unit. The time at which each exposure unit is actuated is modified by a respective time factor so that a dot produced by each exposure unit matches the ideal dot location thereof.
