I have adobe and use to be able to hide scribbles and writing from our staff on a document, save to adobe pdf and print and the scribbles would be hidden. Now when I try that it won't hide the scribbles and it prints all the crap they wrote when I don't want the client to see their notes. It should be written in clear writing, then I usually add text.
It stopped working last week after the last update.
In the Print dialog, under "Comments & Forms", make sure you select the "Document" option.
