Abstract
Data in the host device that was processed before a data interrupt process could run, and data that was already being sent to the printer, can be reliably deleted when an error occurs. A printing apparatushaving a normal processing mode for storing data sent from a host deviceto a receive bufferand running a printing process based on the data in the receive buffer, and a deletion processing mode for clearing data in the receive buffer, has: a processing mode selection meansfor selecting one of a first processing mode for saving data in the receive bufferand print buffer, and not changing to the deletion processing mode, when a printing apparatuserror is detected in the normal processing mode; a second processing mode for clearing all data in the receive bufferand print buffer, and changing to the deletion processing mode, when a printing apparatuserror is detected in the normal processing mode; and a third processing mode for clearing data in the print bufferand saving data in the receive buffer, and changing to the deletion processing mode, when a printing apparatuserror is detected in the normal processing mode.
