Can I set font size on pdf for printing?

I need to print some pdf files. I use Kpdf and, Adobe Reader.
Is there a way to check the font size of the file and to set the
font size I want for printing?

thanks

I don't run either of those apps, so can't speak on them specifically but have you tried changing the "scale" size in your printer settings when you go to print a pdf document?

Don't know that it will work, but maybe worth trying.
