Use an old driver (for OSX 10.3) in a new mac (OSX 10.8/9) I have a printer (Sansung ML-1250) that has driver for OSX 10.3 but now I have a new mac with OSX 10.9 and I'm not sure how to handle it.

Is there any solutions?
You are in luck. Your printer is supported by the Gutenprint open source printer drivers. 

http://gimp-print.sourceforge.net/MacOSX.php

Install these and you should be OK. You may find not all functions of the printer are supported but usually with Gutenprint they come close.
