Function:
1) The position management coordinate system is set by taking as its origin on the Y
axis a position spaced in the positive direction by (256 x tH + tL) x (page
management units) inches from the origin on the Y axis of the page management
coordinate system. Further, the bottom margin is set at a position spaced in the
positive direction by (256 x bH + bL) x (page management units) inches from the
origin on the Y axis of the position management coordinate system.
2) The printing position in the Y direction is shifted to the origin of the position
management coordinate system. At this time, the origin on the X axis is not
changed.
3) If the distance from the origin on the Y axis of the position management
coordinate system to the bottom margin position is greater than the page length,
then this distance from the origin on the Y axis to the bottom margin position is
set as the new page length.
4) If the paper which is inserted is cut sheet paper, then the distance from the top
margin position to the bottom margin position is set as the page length.
