I'm playing around right now to see if I can make some simple instructions....... I'm here http://maps.nypl.org/warper/maps/14834#Export_tab and it's downloading to paint shop pro. It must be huge because it's taking a couple of minutes. I assume once I download I can open it and choose what size I want to print. Are you going to print it as a poster on your printer or send it out to be printed on one sheet?

Maps for your TV wall? Super great idea!! I'd be interested in that kind of info too. Remember you can go smaller, but can't enlarge an image that has a predetermined print size. Well, you can, but it won't look good. You can take pixels away, but adding them has poor results. The more pixels the better. You can get away with +/-100 pixels per inch. So, 50 inches is gonna a big file.

I opened it in irfanview http://download.cnet.com/s/irfanview/

It looks like I can choose what size I want to print it as. I used to do this kind of thing all the time and it was easy. Use it or loose it. I've pretty much lost it. And the $$$ software to make it possible. Irfanview is free. I've gotten away from using it so every time I need it now, it's a whole new learning curve.

My other printer will let me choose the size, too.

Thank you guys!!!

Those are large files which is a good thing. I just downloaded one that's +50 mb. That should give you plenty to print large. The site isn't very intuitive. :) The two maps I downloaded aren't flat, so clearly there's some process (rectify?) that is needed. Maybe more hands-on than you'd like?

Cheap as I am I had mine printed as a colored engineering print by Staples for about 10.00. Original was kind of sepia colored.
