How do you print it front and back?
I would modify the line about no unsafe conviction involving a "handgun" to say "firearm or weapon". If I were an anti I would think maybe you have been convicted of a rifle offense and can carry a handgun instead. I know it makes no sense but do most of their arguments?
Load first file, print, load second file, and reload business card stock into printer opposite side up then print second file. Make sure you feed the correct end first--the business card stock is tapered on one end.
