Not centered with code as written.

Not centered with XOffSet = XOffSet - 0.25  , but closer to being
centered.  I must remove 0.5 inches to get correct centering.

Printer:  HP DeskJet 1600CM

IDL> help, !Version,/Str
** Structure !VERSION, 5 tags, length=40:
   ARCH            STRING    'PowerMac'
   OS              STRING    'MacOS'
   OS_FAMILY       STRING    'MacOS'
   RELEASE         STRING    '5.3'
   BUILD_DATE      STRING    'Nov 10 1999'

margins were honored in the background.  of course there are many things
that I have assumed...
