Zusammenfassung: | A printing apparatus receives printing data from a host device (1) and is configured to selectively switch between a first state in which it is ready to print said data and a second state in which it is not ready to print said data, and to notify said host device (1) of the currently selected state. The printing apparatus (2) comprises: one or more detectors (28, 29) for detecting depletion or absence and replenishment or presence of one or more consumable materials (10) consumed by printing said data, and for causing said printing apparatus (2) to enter said second state in response to detecting depletion or absence of one or more of said consumable materials (10), a controlling device including an operation key (14) that can be manually operated to cause said printing apparatus (2) to perform a primary function or a secondary function, and a function selector (28). One of multiple modes of control is selectively assigned to said operation key, said modes of control comprising a first mode for causing said printing apparatus (2) to perform said primary function and a second mode for causing said printing apparatus (2) to perform said secondary function. The function selector (28) selects either said first or said second mode of control in response to predetermined states of the apparatus.
