I have a few tables and graphs that I want to export to a PDF file using Export[....,"PDF"], but I would like to be able to print this PDF-file and still be able to read it. So how can I control the width etc. of the file such that it fits on A4 pages, and how can I e.g. insert page breaks?
You can get more Information from: Page Layout & Printing Control
On Menu -> Printing Settings and ff you can interact with the Printing Environment. Distinguish carefully which Printing Environment you choose and select the appropriate page size.
With Menu -> Insert -> Page Break, you can set up these.
