The invention enables a print job cancel from a printer panel and an avoidance of a waste print. Also, the invention enables the waste print even when a network emergency occurs. A printer which receives print data from a host and prints an image corresponding to the print data, includes: printing cancellation means which, during the printing of an image corresponding to received print data, in response to a printing cancellation request operation on an operating (S40) panel of the printer, halt the printing, perform discarding processing (S70) of the received print data up to a code which indicates a predetermined end-point, and transmit a data cancellation request (S90) to have the host halt a transmission of print data; and internal reset processing means which, in response to a reset command (S100) transmitted from the host in response to said data cancellation request, perform an internal reset processing (S120) to scrap received print data and transmit to the host a status response (S110) indicating that cancellation is underway. Since the printer halts printing and perform discarding processing of the received print data up to the predetermined code, it is possible to avoid the waste print.
