Many thanks to those who responded to my query about compressing PostScript
bitmaps output with the "image" operator.

Alas, all the responses (and there were several good ones) gave various methods
for compressing the original image data, and then decoding it either in 
PostScript itself, or just prior to sending to PostScript printer.  My problem
is not the original image files, but the amount of sheer data being sent to the
printer.  I want to be able to cut down on the number of bits I actually have
to send down the pipe at 9600 baud.  I gather that there really is no way to
do this, since no one else seemed concerned with the transmission time.

If anyone knows a way to send less bits and have it all come out looking right,
please let me know!!

Thanx,
