Does anyone know how to install the PDF printer? Like when I have a Word file and to make a PDF out of it, I click on the PDF icon and it brings up a lists of programs, then I press cancel and a windows pops up saying, "PDF Maker could not locate the Adobe PDF printer. Please install the printer on this machine". I already have Adobe Acrobat installed. I once saw at an Apple Store in the Print Center they had the PDF printer istalled, but I don't got that printer in the list....any ideas???? Thanks!
