I know its the printing step that is the culprit, but I don't know how to fix it. I printed some images from xv and they look like crap compared to what I see on the screen. AFAIK screen resolution is always 72 dpi regardless of how big the monitor is.

I think the printer is more at fault then the image at that point..

DPI is really a *bad* term. You see, where is there a reference to an
'inch' in a digital image? I'd imaging that xv is figuring out the size
of the image, compared to the size of your screen. I mean think about
it.. Do my images magically have a higher DPI when displayed on a higher
resolution monitor?

What application are you using the print these images? What printing
system are you going thru? And best of all, what printer are you using?
Remember, just becouse a printer can print at 600 DPI doesn't mean the
application is giving it information at this level..
DPI is simply the number of pixels in one inch.
