When sending labels to these printers they will at random print 2 labels on the same label (it would often be last half of first label and first half of last). It may also skip and label and then print that label as a blank label and then print the next label. I'm using Seagull Scientific Bartender program. All the drivers and service packs for Bartender have been installed. The newest version of Zebra firmware has been installed. We've been able to reproduce this on multiple QL 420 Plus printers.
Most likely to do with sensor --- label has a notch in it it in middle make sure it is clean --- do labels have a hole that align with sensor?
Look at Cleaning printer to locate sensor

This printer has capability to print on labels. Here are some tips when printing on labels:
· Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that the labels can withstand temperatures up to 210°C (410°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions.
· Labels can be printed at a higher fusing temperature up to 220°C (428°F) if Label Weight is set to Heavy.
· Select this setting using the Embedded Web Server, or from the printer control panel Paper menu. Label adhesives, face sheet (printable stock), and topcoats can withstand up to 25-psi (172-kPa) pressure without delaminating, oozing around the edges, or releasing hazardous fumes.
· Do not use labels with slick backing material.
· Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and cartridge warranties.
· Do not use labels with exposed adhesive.
· Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label.
· Be sure adhesive backing does not reach to the sheet edge. Zone coating of the adhesive at least 1 mm (0.04 in.) away from edges is recommended. Adhesive material contaminates the printer and could void the warranty.
· If zone coating of the adhesive is not possible, remove a 2-mm (0.06-in.) strip on the leading and driver edge, and use a non-oozing adhesive.
· Portrait orientation works best, especially when printing bar codes.
· Use only paper label sheets. Vinyl, pharmacy, and dual-sided labels are not supported.
