I've looked at the manufacturer page. There is a driver there whith 14MB in size. So I conclude the PPD file is simply not enough. Download the driver
if you haven't already done so and follow the instructions (note you need root privileges to run autorun). Then, if the programm doesn't do it itself, install your printer again, but do select your exact printer modell (should appear in the list), not RAW or something else. You won't need to specify a PPD file neither.
Note: by following Samsung's instruction, your unpacked files can not be deleted as user. Better run the "tar" command as normal user if you are working in your normal user's folder. Then get root privilege to run the programm and change file permissions if needed.
