dpi = dots per inch ppi = pixels per inch lpi = lines per inch to know the minimum you need to scan you'll need to know what sort of dpi your printer is capable of printing. Lets say its an ink-jet that'll handle 1000dpi To print an 8x10 without having to scale the image up or down to make it fit you'll need to scan... 8000 x 10,000 pixels! Pretty easy eh? Depending on the software you're printing with you might be able to get a decent print from less. If you're going to be retouching the scan you might want to scan at double or triple the resolution of your printer so you can make really fine corrections and then scale the image down to the maximum size your printer can handle right before you print.
