You don't need to do anything at all.  MapServer generates raster output =
images that are X pixels wide by Y pixels high.  When you print them, if =
you print them at a high resolution, you will get a small, high-quality =
image.  If you print them at a low resolution you will get a large, =
low-quality image.  If you need an 8.5 inch by 11 inch 300-dpi image, =
make one that is 2550 pixels (8.5 x 300) by 3300 pixels (11 x 300), =
print it at 300 dpi, and you will get what you want.

Is it possible to change image resolution other way than changing the =
constant value (72 DPI) and recompiling mapserver? I need to increase it =
 for generating printed maps.
