Unable to print with Samsung ML-1510

[Agustin <verycoolman@mail.com>]

Hi,

I'm having trouble printing with my Samsung Laser Printer. I go to
http://localhost:631/printers and logon with root password and install the
printer, which is detected on USB1, using the ppd for ML-1510/1710. I am
obviously not doing it right, as when I request a test page the printer
remains silent.
Does anyone have a good idea on this one?

Many thanks,

Agustín
