What causes character height changes in PDF files?

Prior to version 11.1, when using internal Acrobat fonts the PDF Print Driver varies the point size of each text string so that the width of the text string matches the original document. Since most fonts are not an exact match for the internal Acrobat fonts, this problem can occur whether you are using the fonts licensed with our software or someone else's.

Version 11.1 introduces a new way of using internal Acrobat fonts that maintains the original font height and string width characteristics.
