After seeing the maps on the blog the other day, I was wondering if it would ever be possible to produce the mape files in a higher resolution so that you could print them at 1" per square on the map.
While I second your opinion, I would expect a map that size could be quite large for many encounters. A typical printing area allows 8"x10" roughly so battle maps could only be made to fit inside a 40x50 foot area. Many fights could be done in that size, but a lot would not.
What I have done so far is to tell whatever aplication I'm using for printing to splash the file across multiple pages. Then I get busy with scissors and tape. It's a pain in the a$$ but my players have enjoyed the results. You could also take the file to a printer that has a large format color printer. I've seen stuff six feet wide come off of those, but it's pricey.
I'm all for higher res digital maps, too. I love printing stuff out and putting them down on the table. I build a lot of cardstock scenary, so having to print 10-20 sheets (or more!) for a single encounter doesn't phase me in the slightest. But printing blurry maps when you upscale the graphics to that level does. :)
