ABSTRACT:
A printer once stores input data in a buffer memory and then sequentially reads them out for printing. Whether the input data is predetermined one is determined and, based on the result, the sequence of input data stored in the buffer memory is changed. Even in an auto-back mode of operation, the printer prevents a host system associated therewith from erroneously detecting a printer error to stop a job thereof.
