Interface device of printer

Abstract

Abstract PURPOSE:To allow a page printer to be converted for multipurpose with advantages in terms of cost by reading simulated font data or font data in accordance with input data, developing this data on a bit map memory as dot data, and reading/outputting it in a specified sequential order. CONSTITUTION:A bit map control section 4D receives record information to be transmitted from a host computer 1', and if said section identifies serial data as protocol serial data for a wire dot impact printer, a data writing section 4b selects a simulated font memory 4H, and sets a decision storage area for font data on the bit map memory 4A of the data writing section 4b as one which corresponds to simulated font data. In response to a plurality of serial data which is entered from the bit map control section 4D, the data writing section 4b reads the simulated font data from the simulated font memory 4H using each serial data group as simulated character codes, and writes the simulated font data in the bit map memory 4A. Then the data writing section writes the simulated font data in the bit map memory 4A and reads/output it in a specified sequential order.
