Abstract
A printer with a peeler mechanism 1 for peeling labels from a web, the printer having a movable web pressure roller 24 which may be moved from a web pressure position 24A in which pressure is applied to a platen roller 20 to a retracted position 24B in which pressure is not applied. The printer also has a photosensor 21 and photoreceptor having an emitter/receptor surface 21a for detecting the presence and absence of labels peeled from the web. A window 22b in the label guide surface 22a becomes covered to shield the photosensor output for defining a no-label detection stateWhether the peeler mechanism is set to operate in the label peeling mode or is set to a retracted position defining a non-peeling continuous label dispensing mode of operation can be determined based on the output of the label detection photosensor 21, and the label dispensing mode can be set to the label peeling mode or continuous label dispensing mode based on this determination.
