Expert Tip

For step-and-repeat work (labels, tags), set columns and rows to maximize sheet utilization. Turn on auto-scale so the engine fits the most repeats without manual arithmetic.

Double-sided is not available in step-and-repeat mode. If you need back-printing, switch to normal booklet mode.
