Just noticed in your post that you didn't actually say what size of paper the image was printed on (i.e. we don't know what ppi your image was printed at). Since the file default is 72 dpi, Photoshop will just tell you a size by taking the pixel dimensions/72. Also, you say you see pixelation on textures. Are these mapped textures and is the pixelation "in" the image or on the print out? The higher resolution you render, at a higher mapped image resolution is required. -karl
