Drawer #1 Opens for all cashiers: This option accomplishes two things: first, this option disables the second cash drawer, and second, in full service mode, it will open the cash drawer for any user closing a check.
This option is used in quick service mode to disable the second cash drawer in restaurants that are only using one cash drawer per terminal (MicroSale has the ability to use two cash drawers on each terminal allowing two users to track and store cash separately). This option can also be used in a full service application where two or more users share a cash drawer but track sales separately for tip tracking purposes.
