Badia PrintPreview (formerly, a component of Badia Printools) is a free XTension for QuarkXPress 8 that displays a live print preview
attached to the Print dialog. This preview gets updated in real time as you
change the print settings, giving you immediate feedback as to the way those
changes will affect the final output.
Most print parameters are shown, including spreads, print marks, manual or
automatic tiling, page rotation, bleeds, page gap, flipping and negative
printing. You can also manually tile a page simply by dragging the mouse over
the preview.
