This Samsung ML-85G printer driver can print at
the full resolution of 600x600 dpi, and at the
maximum speed (about two times faster than the
driver supplied by the manufacturer under
Windows). It needs Ghostscript to convert your
PostScript files into PBM images, piping the output
directly to the driver. The driver runs in user
space, but calls iopl(), so it should be set suid root
to execute transparently.
