IE a 17 page PDF file is 3.6mb
Previously a a 74 page PDF file was 378kb.
I’ve tried adjusting all compression settings, etc but have had no luck.
I am using PDF Creator 2.3
this is most likely related to the printing application, were you using a different version of the printing application on the previous Windows system?
it could very well be. Did you also have PDFCreator 2.3.0 on the previous system, or was it an older version?
