I printed mine out on my HP Deskjet 970Cse printer. It always outputs great results. You just have to make sure your orignal scan is a high enough resolution to begin with (don't shrink it). My covers also always live in an uncompressed format like TIFF or PSD. I never make JPEGs out of them for printing. My Gate of Thunder insert is 2356 x 1841. Print that out at the slowest, highest quality possible on some good paper (though not so thick that it can't fold) and you'll have something that would be better and have a higher resolution than a real insert.
