i have some annoying problem in printing after i've upgraded to FileMaker 12v2.
If i try to print a report with some container field that has particular setting to image content (ie: constraint size, expand) , the result is a blurred image.
I attach an image for clarify.
Left 12v2, right 12v1.
Try going to File > Manage > Containers > thumbnails, and unchecking the "generate thumbnails" checkbox to see if that corrects it. If it does, try flipping that to temporary storage instead of permanent storage. You might also try deleting and re-adding the container object on your report layout.
