ABSTRACT:
A printing device employs a printing drum on the peripheral wall of which a plurality of character types are arranged in the axial direction and in the circumferential direction. The axial movement and rotation of the drum are independently controlled by comparing the position of a new character type on the drum to be printed with that of the immediately preceding one of already printed character types thereon at each printing step in response to electric printing information. A hammer is disposed close to the outer periphery of the drum. The hammer advances step by step in printing in the axial direction of the drum independently of the drum to determine the printing position with respect to a record sheet and selectively strikes the opposed surface of the drum through the record sheet. The printing device can thus attain a mechanical driving system for the drum and hammer which has the simplest construction, the least probability of trouble, and a highest possible printing speed with ease.
