It might not be worth the cost, but if you used a color duplex printer, you could print the badge on both sides, as well you would not have to have the badge paper printed up (same with just a color printer). This would reduce the waste of paper ,or having badges from Scale 12x hanging around (yes, I saw that stack).
It would also give an option to print special, noticable badges for any purpose, such as tech, a/v, volunteer, speaker, expo, etc.
I am not sure of what the cost would be for the printers and toner vs. having the badges printed up.
