However, people unfamiliar with POS hardware may find all these new items a little confusing. Each receipt printer comes with one or two cash drawer ports for direct attachment. Several options are available for most receipt printers, including journal take-ups, cutter mechanisms, slip validation and MICR units. The cash drawer is another necessary component in any point of sale system.
Most cash drawers are printer-driven.
Each receipt printer manufacturer has a unique cash drawer interface, making each cash drawer printer-specific. Cash drawers may also be attached independently via serial or parallel port. Magnetic stripe readers are convenient for retailers who want to accept credit or debit cards. Proper software and a modem are needed to fill out the solution. Keyboards have various configurations for the point of sale environment.
