Is it possible to export the game pieces I’m making to some sort of easy-print format?
Images from GPIs are saved in the module as PNGs; you could fish them out of the module’s images
directory.
Great! Thanks! Now to find a program that can plop them into the proper size and spacing for POD services.
Inkscape, which I have used for a few years, can do that. Inkscape is offered free, but it has a learning curve.
You could do that with ImageMagick.
For simple graphics I use PhotoFiltre (7). For more difficult stuff I use GIMP.
