A printing device such as a printer of the type using a type wheel in which a carriage is loaded with a printing mechanism and movable along a carrier to allow the printing mechanism to print out data on a paper, which is wrapped around a platen. The carrier and/or the carriage is produced by press-forming a single sheet metal to cut down the production cost and the number of structural elements of the printer.

Printing device with carriage and carrier therefor each integrally

A printer capable of operating in a bidirectional printout mode by converting a print code to pattern data and using a print head in which print elements are arranged in a plurality of arrays. A buffer control is provided for controlling in a ring structure entry and retrieval of pattern data into and out of an image buffer. A detachable font cassette stores the pattern data and data associated with print configurations. A pattern data store stores print pattern data in blocks for each of the print element arrays.
