I have a problem converting a word document to PDF without it reformatting the page. It looks to me that the issue happens only on pages that have a word table at the bottom of the page. When I select to print to Adobe PDF or if I use the add in button. The page readjusts and moves rows from the table onto another page. I have check all printer settings. I have scaling turned off and all are set to 8.5 x 11 sheets. I was curious if there is a setting I am missing or a fix for this problem. I have noticed that this only happens on files that have tables at the end of a page that has footers.
In Word, you can have an overlap - go to paper - all is well. To get your output PDF you pass through Distiller, were the processing is, well a wee bit more rigorous. What worked for me was reducing the footer height to give a clearly defined "break" (no overlap). Perhaps it will help in your situation.
