I've been using PDF-XChange Viewer for 2-3 years after getting tired of Adobe's Reader.

I noticed back in December (yes!) that the Viewer didn't honor the PrintScaling=None setting within PDFs when testing a template that needs to be precise without print scaling/Fit to margins/etc. Same result with the Editor. (Firefox's own PDF.js viewer also had this problem at the time, but it's been fixed I think. Chrome's is OK. Other PDF viewers were also broken, except Adobe.)
I wasn't messing with printing templates and thinking about it again until the summer, and never came around to post about it.




Thanks!
