Printing Problems
Even after changing the page length or margin positions, you find that
the printed position is not correct.
You may need to set the printing position with the T-OFFSET or
L-OFFSET settings in the SYSTEM CONFIG menu of SelecType
Level 1. This feature allows you to adjust the position of the
printable area on the page. See Chapter 4.
