Good afternoon, I have a project in c # that when you print from a receipt printer connected by usb also open your money drawer that is connected to the printer. I managed to print but not to open the cash drawer.
printer details: NCR 7197 RECEIPT (this has a port that connects the cash drawer).
I tried using APIs (Windows. Devices, Point Of Service, ePOS-Print API) but it is not functional.
here I leave you link of the project:
