I'm trying to print a pdf document but with 2 pages per sheet. I tried to scale up the document by 10% (in the page setup tab) but it actually scaled down about 30%. Any idea what could be going wrong? Can Adobe even scale up and print multiple pages on the same sheet?
Are you using the Multiple button under the Page Size & Handling section of the Reader Print dialog? This section allows you to determine how many pages are printed per sheet. The scaling is pre-determined by the number of sheets you have selected.
