I got a new MBP with Mountain Lion and Acrobat Pro X. In my old Mac, I could set the printer settings to grayscale and print PDF files w/o color. With the new OS and Adobe, when I click the Print button and then OK, the document is printed in full color. To print in grayscale, I have to go File>Print>Printer>OK for each document. I have been going in circles over the web with no success. Can anyone help? PS= In my old Mac (Leopard and Acrobat Pro 9) there was a virtual Acrobat PDF printer. Now, it's gone. Would that give a hint?
