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 24 A in which pressure is applied to a platen roller 20 to a retracted position 24 B in which pressure is not applied. The printer also has a photosensor 21 and photoreceptor having an emitter/receptor surface 21 a for detecting the presence and absence of labels peeled from the web. A window 22 b in the label guide surface 22 a 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.
