First select the non-contig ranges by dragging range1, then holding your control key down and dragging range2, then range3... etc., until all non-contiguous ranges are selected. Then File/Print Area/Set Print Area will "lock in" your selection until you choose to clear it.
This process will print each range on a separate sheet. I have not been successful in printing them all on a single sheet, but someone here will undoubtedly offer a solution. Cheers!
