Updates in v1.5
All screenshots and features described are for ORO POS 1.4. The following section describes some changes in ORO POS 1.5.
Added “Cash Drawer” Button on the ‘Configure this terminal’ window.
Added dual cash drawer support in a single terminal. To set up cash drawer settings, go to Back-office-> Admin-> Terminal configuration-> Cash drawer tab.
There is three option for cash drawer settings. These are:
- No cash drawer
- Single cash drawer
- Dual cash drawer
No cash drawer:
If no cash drawer is selected, then the cash drawer cannot be assigned from this terminal (there will be no ‘assign drawer’ button in the clock in/out dialog). However, tickets can be created from this terminal, but payment cannot be taken from this terminal unless the user has an active staff bank.
Single cash drawer:
If a single cash drawer is selected, then a drawer can be assigned for this terminal to only one user. If the cash drawer is assigned to a user then that user and all other user’s payments will go to that cash drawer except the user has an active staff bank.
Dual cash drawer:
If a dual cash drawer is selected, there will be two cash drawers (primary cash drawer & secondary cash drawer) for this terminal and can be assigned to one user each. If any cash drawer is locked to a user then that user’s payments will go to that cash drawer. All other payments will go to another cash drawer except the user has a staff bank.
