Test prints from the computer show as completed, but there's no actual printing and no error message. Pressing and holding the power button causes a test print, so I know that physically the printer works. When I connected the printer with USB cable the following driver was automagically installed: Samsung ML-2550 Foomatic/Postscript (recommended) also: ML-2510_Series (Default Printer) Description: Samsung ML-2510 Series Location: Printer Driver: Samsung ML-2550 Foomatic/Postscript (recommended) Printer State: idle, accepting jobs, published.
