A printing apparatus has a transport module with a moving transport belt tht transports strip-like print media past a printhead for printing thereon. Specifically, the semiconductor substrate has at least first and second device regions of different surface crystal orientations. The method also includes determining a plurality of coordinate pairs, where each coordinate pair is associated with a point from the plurality of points. When the data packet is received via a first port, the processed data packet may be transmitted via the first port, or may be transmitted via a second port. wherein A, R1, R2, R3, R4 and R6 are as defined in the specification.
