thanks alot.Graphics DPI Question?
Basically the answer is you can't do that. Even if you first printed out the image, you would have to print it very small, because of its low resolution. Enlarging it on a scanner is not going to give you very good results, and in fact may even be worse than just attempting to enlarge it in a digital image editing program (Photoshop or Paintshop Pro or any other one). There are software plug-ins that can improve this, but they are not cheap (I just acquired the On-One set of plug-ins for Photoshop and will be experimenting with their Genuine Fractals, which is pretty good at such enlargements).



A 5 x 8 72 dpi image is going to of course look like crap when printed out, since it's low res. If you reduce the size to improve the quality, it will be so small that scanning it after printing will not be much use.
