Notes:
If the reverse line feed value exceeds the Top of Form position or the top margin, the
print position will start at the TOF or top margin position.
If the forward line feed value exceeds the bottom margin, the print position will start at
the top margin position on the following page. If Skip Over Perforation is set and the
forward line feed value exceeds the skip over perforation area, the print position will
start athe Top of Form position on the next page.
