PRINTER, METHOD OF CONTROLLING PRINTER AND RECORDING MEDIUM RECORDED PROGRAM THEREFOR

摘要

PROBLEM TO BE SOLVED: To reduce CPU's load during the process which stores received data on receiving buffer. SOLUTION: In the case that any receiving error exists on the received data, the received data producing receiving error are canceled and replace it with an error letter '*' in an data receiving process to a serial interface circuit 20 which is executed on a CPU 60. And the error letter '*' is output from the interface circuit 20 as print data. Thus the data, which is output from the interface circuit 20, can be stored on the receiving buffer 49 by just transferring it.
