| 1. A printer adapted to be connected to a host computer and to receive data including control commands from the host computer,
the printer comprising:
a receive buffer that temporarily stores received data;
a data interpreter that interprets the data in said receive buffer;
a controller responsive to said data interpreter that controls said printer;
a state detector that detects whether said printer is in a first state in which data is received and the received data is
not printed, or a second state in which data is received and the received data is printed;
a clearing unit that clears said receive buffer, the clearing unit being adapted to automatically clear said received buffer
after said state detector detects said first state and before detecting any condition for exiting said first state; and
a data discarding unit that discards print data received from said host computer while said printer is in said first state.
