First, i thought it may have something to do with 64 versus 32 Bit Data
types corrupting lpvi* structures in size and layout, but that was not 
the case.

I then found out that doing the following change to gsdevsppr.c
----- FROM:
lpvipage.resolution = (pdev->x_pixels_per_inch == 300 ? DPI300 :
DPI400);
----- TO:
lpvipage.resolution = (pdev->x_pixels_per_inch == 300 ? 300 : 400);
-----
helps - it now prints fine!
(even this is contrary to the manpage of lpvi ...)
