Unlike an ordinary line feed code, code ESC J does not advance the paper to the top of the next page when the print position enters the perforation area (Perforation-skip operati- on is not performed). The value specified for n must be in the range of 0 to 255. This code sequence does not affect the amount by which the paper is advanced by subsequent LF or VT codes.
