ABSTRACT:
There is described a printing apparatus, particularly a label printer, which includes a switching mechanism operable in response to movement of the lid to permit operation of the printing apparatus only when the lid is closed. This can be combined with detection of the presence or absence of a cassette in a cassette receiving bay of the apparatus so that operation of the printing apparatus is permitted only in the presence of a cassette and with the lid in the closed position.
