contact the supplier from where you purchased
the printer.

printing media?

picture postcards?

surfaces which have a non-uniform thickness.
Printing and feeding of thermal paper is
unreliable. The back side of picture postcards
may be printed on if the surface is smooth and the
card thickness is 0.23 mm (0.01") or less, but
