A thermal printer comprising a print head having many thermal resistors, a movable carriage with the print head mounted thereon, and a ribbon cassette mounted on the carriage. Print data transmitted from a host system, such as a personal computer, in the form of character code is conducted through a processor into character buffers separately for each line, the print data are transformed into dot-matrix data by character generators CG(L) and CG(S), the converted dot matrix data for two lines are stored through the processor into a dot line buffer, the contents of the dot line buffer are transferred to a shift register, and a head driver for the thermal resistors is activated in response to data from the shift register.
