PROBLEM:

Jpeg images do not print correctly. They print as two tone images with no grey
scaling. (We are trying to print digital mug shots.) We are using an HP5
Laserjet with a jet direct card on a Novell 4.11 network. This problem occurs
on Windows 95 workstations, BUT NOT on Windows NT. The image prints fine on NT.

This is the most simple source code I could come up with, but the problem occurs
in any program we have tried. You will have to provide your own jpg image.

When the program launches it will display the jpg image in the frame. Simply
close the frame and the image will print. It does not display the printer
dialog, but you could add that if you want.
