<p>A printing apparatus for connection to and control by a host device (120), comprises an interface circuit (102) for receiving control commands, print data and reset signals (Vrst) from the host device (120), a printing mechanism (104), and a controller (103, 105, 106, 108) for controlling said printing mechanism (104) in accordance with said control commands, print data and reset signals so as to print text or graphics on a printing medium. The controller is adapted to perform a predetermined initialization of the printing apparatus in response to a reset signal (Vrst) received by said interface circuit (102). Measuring means (103, 107) for measuring the duration (Tr) of each of said reset signals (Vrst), are provided and the controller performs one out of a plurality of predetermined initialization processes selected depending on the duration of a respective reset signal (Vrst). <IMAGE></p> |
