Abstract
In one example, an apparatus is described, which includes a platen locating the print medium, at least one printhead for marking on the print medium, a carriage holding the at least one printhead, a sensor at least partially mounted to the carriage to measure a printhead-to-platen spacing (PPS) along scanning axis during scanning, and an integrated circuit including a dynamic compensation module and a PPS analysis module to delay firing of printing fluid drops from the at least one printhead to compensate platen defects based on the measured PPS.
