Home Forums Peripherals & Multimedia Peripherals Can't print PDF files

Using Adobe Acrobat Pro (Adobe Acrobat X 10.1.1) with Lion (10.7.2), I can open but cannot print PDF files.
My printer (Lexmark e120) has no problem handling all other types of documents. But when I select PRINT for a PDF file, the printer icon will show the number of copies chosen (indicated by a red circle with white number inside) and then just not do anything (whereupon the red circle disappears); nothing shows up in the printer queue.
All software has been updated to latest versions.
Any suggestions?
