I wonder about the final file format when exporting an image from Poser. So far, since I render at the max 4000 pixels, then reduce in Paint Shop Pro, I've not run across any loss of details in the render. Especially since I'm using a home printer. However, I have read that it is best to use a PNG if printing an image with sharp edges (like a bunch of letters), otherwise, JPGs will work fine. Since a majority of my printing is on home-inkjet printers that are limited to 8.5" x 11" sheets, resolution issues haven't affected the images yet. But should I ever hope to print commercially (yeah, right LOL), then the issue of file format would probably be very important.
