We still also have the same Problem with our ESA AsyncOS Version 15.5.
When a Document it's safe printed, than the printed document looks like it's printed in A5 Format and than added to a A4 Format sheet. The result is a very small safe printed area of the content (where it's hard to read anything) and a huge white border around the safe printed part.
So hopefully any Cisco technician will look at this bug soon.
