Abstract
PURPOSE:To transmit the error information and set information of a printer and various information by adding a serial transmission signal line to a parallel interfacing device of a printer communicated with a master processor through plural signal lines. CONSTITUTION:A microcomputer 2 controls the internal processing of a printer 1 and a handshake control circuit 3 inputs data on a data line to a latch circuit 4 to enter the data to the computer 2. The master processor 6 is controlled by a microcomputer 7 and the computer 7 transmits data in a latch circuit 9 to the printer as transmission data through an external connector and a connection cable 11 based on information from a handshake control circuit 8. A serial data transmission circuit 5 is connected to a serial data receiving circuit 10 through a cable 11. Paper cutting, paper jamming, ribbon abnormality, and other error information generated in the printer 1 are detected by the computer 2 and can be transmitted from the circuit 5.
