I just downloaded one and, unless I’m missing something, the file is missing the usual, “Permission to print for personal use….” text.
Perhaps Paizo has a standard statement somewhere else that these can be printed? Without the ability to print these I’m unsure, outside of VTTs…maybe, what their use is for GMs.
I purchased one to try out, and was planning on having it printed on a large-format printer at Kinko’s. However without that statement/release I can’t see any commercial provider touching these for printing.
It’s supposedly being rolled into ORC that you may use any and all artworks in the PDFs and other published materials for personal use, be it printing, displaying, etc. I’m sure someone will correct me if I’m mistaken though.
