I upgraded to SL and my Brother HL-1470N printer is missing. I went to the Apple site and there they let me know I need Version 4. I went to the Brother site, downloaded and installed it and still the same. I installed Gutenprint also. I now managed to get my printer name in the window, I can select the printer for print, but the print queue is empty. No print. I selected the latest driver Brother HL-1470N series CUPS. In the printer setup I see "URL: pdf800://distiller" and this worries me. In Options & Supplies, I can select any driver I like, nothing works. Paul Moortgat
