ABSTRACT:
A printer having plural type font wheels for function symbols of different colors and plural type font wheels for numerals of different colors fitted on a rotary shaft, wherein the plural type font wheels for numerals are displaced along the shaft for each printing action. The plural type font wheels for function symbols or for numerals are provided with a mask for exposing only one type font wheel of a desired color but covering all other wheels to enable multi-color printing. The selection of the type font wheel for printing is achieved by the displacement of plural type font wheels in the digit direction with respect to the mask.
