Printer driver for samsung 1510

I am probably in the wrong place but here goes. I have a Samsung printer model ML1510. This has worked for years with a macbook pro. I have now acquired an macbook air and the printer will not work. No help from apple, Samsung, or HP (who acquired Samsung). Internet searching says that there is a driver in “open printing”. I searched Splix and came up with the website; and yes there is a driver for this samsung. BUT, how do I down load this; I could not seem to find a file to download. Can anyone give me a Dummies guide as to how to do this? Any help would be appreciated. regards. Charles
