My printer works fine. My MacBook Pro works fine. My wireless works fine. When I send a photo from Lightroom 5 to the printer, I get an error message indicating that there is a communication problem, and that there is a "broken pipeline"...the printer starts to print, then stalls, and then presents the above stated problem issue. Please note, the iphoto application sends photos to printer, and the printer performs flawlessly flawlessly. Word processing (Pages) communicates to the printer flawlessly, and the printer works fine.
