It might be that you're scanning in colour and sending to a b&w printer.
Either the printer or (more likely) the scanner is dithering the
picture, and it's probably down to the settings you are using to scan
the image. I saw this about 12 months ago using XSane and an HP
scanner. Can't remember the setting I changed, I can have a look later
if you get stuck.
