When printing disk labels you may have two solutions: you can print them on plain paper and cut them with the scissors for example, or print them on special CD label paper with already cut edges.
In first case, you will probably want to print only visible part of label with cut lines visible.
In second case, printing of only visible part of label would be inappropriate รป a small mistake caused by imprecise determining of positions or way printer pulls paper, would result with ugly whiteness on edges of label. Because of that, there is possible to print whole (rectangular) label, with both it's parts: visible and invisible. In that case, cut lines are not printed, too.
The way of printing disk labels you can adjust in options dialog.
