Portable Label Printing
There are also portable printers available for bar code label printing as well as pricing or shelf labels. These printers typically
don't have a Magstripe input, as they are designed for label printing only. The classic application is for printing shelf labels dur-
ing shelf price verification:

The operator scans a shelf label.

The Terminal transmits scanned data to the host computer.

The host computer looks up the price, description, etc. and transmits the computer price back and sends the necessary com-
mands to the attached printer to prints a new shelf label with the correct price.

The terminal operator then peels off the label and applies it to the shelf.
Shelf adhesive labels are designed for ease of removal to facilitate replacement. Permanent adhesive labels are designed to stick
and stay stuck, making removal difficult without leaving a residue.
