I requested samples from various vendors who stock thermal ribbons for
zebra printers. I got wax, wax/resin and resin ribbon samples. The
narrowest is 3 inches, the widest is 4 inches (making the widest board
4 inches).
If it were possible to find a solution to get this to work, in my
resources if I look harder I am sure to find ribbons which would be
probably 8 or 9 inches wide.
