I am looking for a program that takes a IFF Dpaint or compatable file and
dumps it directly to the printer without first having to put the image up
on the screen.

The biggest problem with Dpaint, Images and the Dpaint 'PrintUtility' is that
their is no capability to specify the amount of dots to pixels during the print
out.  What happens is that each image is algorized for shading.

	example:	If you had a screen image of 640x200 and were able
			to specify a one dot to one pixel resolution for
			a printout, you would get what you see on the screen

			Obviously the printout of the image would be small
			but it would be accurate.

			This point illustrates why when coloring an area
			the fixed algorythm used, causes the grey scale
			shadding to look 'blotchie'

	solution:	By allowing the user to specify resolution increments
			you can produce a more accurate rendition of the
			image.

			IMAGES attempts do accomplish this by allowing you
			to select X and Y Format Values.  But a known but
			in the latest revision will not allow you to
			select an even value for x and y also, because of
			the slider span limitation, selected values are
			not repeatable unless you reboot.

	*****		To double the size of printout, selecting the
			values  (640x2)x and (200x2)y would double the
			size but would print a blank dot between every other
			x and y dot in the image.


			640x200		.....
					.....
					.....
					.....
					.....

			1280x400	. . . . .
					. . . . .
					. . . . .
					. . . . .
					. . . . .

	Conclusion:	The images would be more grainey, but would be
			true to the image.


	If anyone has written a graphics dump program that follows this
	phislophy, please E-Mail me or post the sources.

	Hopefully, EA Dpaint and AEGIS Images will get their printer dump
	routines in-order.  As of this date, their just a cludge!
