PDF Quality using PDF Print driver on Mac v FMP on PC

We’re having an issue that I hope you can help us resolve. When creating the same PDF document on a MAC v PC using Adobe PDF driver built into the Filemaker Pro we are getting a drastically different quality of document. Originally I assumed it was the original PDF driver installed on the PC itself since it was an off brand “LITE” version so I had the user remove all other PDF software and start from scratch with acrobat. Still getting the same results.  I have no idea if and where quality settings would be found on the PC or in FMP to check those…

Any ideas?
