Bar code label printers drive also means label feed mechanism, there are two kinds of ways using, a print head platen of ways, one is hanging printhead pressure way, way platen roller generally only use the front Driver Feed (some wide barcode machine also before and after the roll axis simultaneous drive), suspended pressure methods are adopted feed mode dual front and rear drive rollers, so the way platen, the print head, labels, front roller in a compressed state, while suspending the pressure mode, the print head, labels, front roller can be pressed in an incomplete state.

Label feed mechanism either way platen, or hanging pressure way, all using the same motor, if it is a twin roll shaft drive, belt drive is generally used double roller, bar code printers principle, this one is the most you can determine barcode a standard printer durability, durability, good bar code printers belt gears are made of metal pieces, ensure the life of the bar code machine at high speed in the transmission structure

Transmission barcode printer accessories, such as bar code printers rewinder, bar code printers stripper, also use the feed mechanism drive motor.
