A label driver in the context of Windows usually refers to a printer driver or software used to manage printing tasks for specialized printers, such as label printers, which are designed to print barcodes, shipping labels, or product labels. These types of printers are commonly used in logistics, warehouses, retail, and manufacturing environments.

The label driver enables the computer to communicate with the label printer, allowing you to print labels with the appropriate layout, format, and size. Without the correct driver, the printer may not function properly or be recognized by the operating system.
