Abstract:
A printing device having a print head, a plurality of rollers which transport a recording sheet past the print head, a sheet detector which detects the presence of the recording sheet inserted into the printing device and an interface which receives data from a host device, comprising:a data analyzer for interpreting the data received by the interface and interpreting a first time parameter as a time duration for positioning the recording sheet in the printing device and a second time parameter as a maximum time duration for waiting for the recording sheet to be inserted;a first timer which initiates transport of the recording sheet after a first time corresponding to the first time parameter has elapsed, when the sheet detector detects the presence of the recording sheet;a processor for controlling printing on the recording sheet; anda second timer which sends a signal to the processor to disable printing on the recording sheet when a second time corresponding to the second time parameter has elapsed, if the recording sheet has not been detected by the sheet detector.
