I have checked accessability and the replace document colors is not checked. For a time after I downloaded reader 11 black text printed black but today it has reverted to green.
I have also tried two other actions. First, copied PDF document to clipboard and pasted in Word document. Word document printed as green text. Second, set printer to print as image. Also printed as green text. This happens with a variety of documents from a variety of sources. It appears the problem is with the download of the file as the attributes seem to be set in the file. All documents appear as black text on the laptop monitor.
