ABSTRACT:
A printer having a ribbon lift mechanism for lifting a ribbon from a rest position to a printing position. The printer operates in two different modes, that is, a printer mode in which characters are printed according to the data in a memory and a typewriter mode in which characters are printed according to the data from a keyboard. The ribbon is returned from the printing position to the rest position when no subsequent data comes from the memory within a first preset time interval in the printer mode or when no subsequent data comes from the keyboard within a second preset time interval in the typewriter mode. The second time interval is preset shorter than the first time inteval in order to print successively in the printer mode and to put back the ribbon to the rest position quickly when an operator needs to check the print on a printing paper in the typewriter mode.
