A compressible stamp includes a housing. The housing has two parts which
are moveable with respect to each other. One of the parts defines an
opening. A selector switch is arranged on the housing and is configured
to select indicia to be printed. A printhead is movably mounted within
the housing. Responsive to relative movement between the two parts during
compression of the housing, the printhead is able to move across the
opening to print the selected indicia.
