	We have PCVISIONplus Frame Grabber board and DOT-X Video Monitor
running with IBM PC-AT. We use ImageTool from Werner Frei Associates
to digitize and store images.  The images on the monitor have the resolution
of 75 pixel per inch and eight bits per pixel.
	We want to print the images on a HP series II laserprinter with the
resolution of 300 pixel per inch.  One pixel on the monitor can be represented
by 4x4 pixels on the laserprinter.  Since there is only one bit per pixel on
the laserprinter, we thought that we could decorate the 4x4 pixels correspondingthe original eight bits depth.
	Has anyone done this before?  What the alogarithsm is used?

	We were told that we needed to buy additional memory expansion module
for the HP series II laserprinter in order to print 300x300 images.  Is there
a way that we can send half image to the laserprinter and have it printed,
then send the another half afterwards?

	Thanks in advance for any help.
