Does anybody know how to send images in binary (instead of hex)
to LaserWriter (using operators image and imagemask) ?

Most of our jobs, 90% of PostScript source are image in hexadecimal.
We would like to double speed by using binary image. 
(Yes, increasing baud rate is another way...)

The printer is Apple LaserWriter, serial, 9600 bauds.

Any help will be greatly appreciated.
