I have a cheap Laser monochrome printer from xerox, Phaser 3116.
Unfortunately, xerox didn’t provide official driver for Leopard.
So after googling for a while, I finally landed to http://www.guigo.us/mac/splix/.

This is a Mac OS X package for SpliX, a set of CUPS printer drivers for SPL (Samsung Printer Language) printers. If you have a such printer, you need to download and use SpliX.
Supported Printers:
Installed the driver, and my printer ready to be abused. 🙂
