WHEN I TRY TO PRINT PDF FILES, THEY COME OUT DIFERENT ORIENTATION, AND VERY SMALL IMAGE, MY PRINTER IS PHASER 6350
If it only happens with PDF, then the issue is Acrobat/Reader/Preview.
With that in mind:
Choose Paper Source by pdf page size can cause weird issues (First page correct, all others a thumbnail at upper left of page)
Orientation settings should almost always be Auto
It isn't mine, just found it online and coverted to various formats to use for example purposes
I do in fact have a cat though ;-)
