Most maps I print in my digital print shop are on photo paper and sometimes laminated. I also print to canvas in sizes up to 42" x 10 feet or more (though that would be quite expensive). I can color laser print to heat transfer paper then can apply that print onto fabric and other kinds of media, however I am limited to the size of my heat press - which in my case is 11" x 15". It is impractical attempting to line-up multiple 11" x 15" rectangles into a larger area with heat transfer. It is nearly impossible to perfectly align, so if a given map doesn't fit in 11" x 15" - I can't do anything about it. So its kind of impractical. Printing to most other kinds of oddball media might be instances of 'coolness', but again, almost always expensive and thus impractical for a means to print all your maps. These are my impressions.
