This post is a reference for anyone on this forum that is searching for driver information for the Samsung ML-2150 and ML-2250 Laser Printers. I own the ML-2250 and I think it's great. I have had no problems with print quality or speed. Also, it looks stylish with the glossy plastic-type finish that serves as the printer's outer shell.
The printer does not say it is Mac-compatible and printer drivers for the Mac are not on Samsung USA's website. But the printer IS Mac-compatible and you can find the printer drivers for the Mac on Samsung Australia's website. The driver for the ML-2150 works for the ML-2250.
