        We are in the process of trying to print a grey-scaled image on
an HP-laserjet, which has an output characteristic of 300 dpi, monochrome.
The image file contains 8 bit/pixel grey scale values.  Although we can
get a printable image using NeWS to do the half-toning, it appears that
a half-toning algorithm used for a CRT display device isn't really cut out
for producing an image tailored for a 300 dpi output device.  Anyone out
there know of a public domain filter that may do this?  A posting or direct
email response would be much appreciated.

        (I did see the recent posting by Ed Falk, containing the two
dithering filters "odither.c" and "fsdither.c".  However, the real question
is, has anyone studied the characteristics of the HP-laserjet and tweeked
a half-toning algorithm accordingly?)

        Thanks (wishful thinking)
