Preview vs print-out

[macavity]

Apologies if this has been discussed before, but I wasn't able to find the topic.

Is there any way to assure that FileMaker's Preview and the printed or PDF result are identical in regard to page breaks? I have run out of ideas and the users at the firm are angry, as precise page breaks are essential for them.

The Preview button contains a page set-up for their printer, for which the latest driver has been installed.

The problem occurs both on Mac and PC, it occurs whether working locally or on the server. The page-break problems don't occur on every page, but for the work they do, it must not occur ever.

I'd be grateful for any help on this.
