Lot's of things don't work right in the PRINTER device. :-)

I'd do something like this to get three images centered
on a landscape page of output:

thisDevice = !D.Name
keywords = PSWindow(/Printer, /Landscape, Fudge=0.25)
Set_Plot, 'PRINTER'
Device, Landscape = keywords.landscape
Device, _Extra=keywords
!P.Multi=[0,3,1]
TVImage, image1, /Keep_Aspect
TVImage, image2, /Keep_Aspect
TVImage, image3, /Keep_Aspect
!P.Multi = 0
Set_Plot, thisDevice

You can learn more about how the PRINTER device works
