Label printer devices are either connected to a separate computer or have in-built keyboards and display for stand-alone use (label marker). They print on card-stock, paper or self-adhesive media.
The most common and efficient label printers are thermal printers which include direct and transfer. Direct thermal printers use heat to produce images on heat sensitive papers. However these labels fade over time from heat exposure, like direct sunlight. Transfer printers make permanent prints by using heat to transfer ink from the ribbon onto the labels. Other common printers are dot matrix and laser.
Printers are commonly used to print barcodes on products in order to ease inventory tracking. In such cases the printers work with a POS program. Staffs are required to scan each product barcode for inventory taking.

Restaurants also barcode take-out forms and bags and printing numbers for customers in waiting.

Barcodes are also used in labelling prescriptions and unit use medications.
