Question about printing portals

[joegez]

I had a layout with a portal with 8 rows that extended over a page boundary. That layout would only print the rows that were on the first page and none of the others.

I modified that layout so the portal started at the top of the second page and extended over several additional pages. I also formatted it to slide up so that unused rows would not be shown or printed. I was then able to get all the filled rows to print even though it took more than 1 page.

Is there any general explanation of why this change caused the print to work?

Many people avoid printing portals. Instead print from the related file (so the records are local and not related) and bring in the main data through another relationship.

This way you can do sliding/printing on fields and parts, something that doesn't work with portals.
