Presented herein is a unique portable electronic hand-held label dispenser that is adjustable to accommodate labels of various widths by lengthening the pins and replacing a lower guide plate, and which additionally incorporates a sensor mechanism that precisely determines the length of each label, in order to accurately advance the roll of labels according to the captured data and dispense a single label at a time, and which includes the added advantage of a unique slotted uptake wheel that efficiently collects the paper backing for easy disposal. Depressing an electronic switch causes a label to be dispensed and also activates the sensor mechanism, which allows a roll of labels to advance until the end of the next label is identified, indicating that the roll has been advanced the full length of a single label, and additionally the uptake wheel rotates to capture the discarded paper backing.
