PrtScn for DOS application in XP, does not work

I have an old, but good DOS program with a graphics
feature. Midway through program execution, the screen is
filled with a graphic plot. Normally, in DOS, Windows 3,
Windows 95, ME, and 98, a "Shft-PrtScn" (screen dump),
will send the graphic image to the printer, via LPT1.

The problem I have is that Windows XP will not send the
graphic to the printer.

I have tweaked the executable file via the "properties-
misc" parameters. But no workee at this time.

Dell can't read English. Microsoft is unapproachable.

Any help from a good samaritan?
