Cash drawer

The cash drawer sits at the register and holds shift cash. In FireMenu you can open it from the POS with one tap or open it automatically after an order is paid—when the drawer is wired to the printer and the right options are on.

Physical setup

With Sunmi printers, the drawer is usually connected with a cable (the cable supplied with the drawer) to the drawer kick port on the Sunmi printer. The printer sends a short pulse to pop the latch. FireMenu does not talk to the drawer directly—the command goes to the printer for which “Cash drawer” is enabled in settings.

Check that the cable is firmly seated and that the drawer model matches what your hardware vendor recommends for that printer.

What to configure in FireMenu

Go to Settings → Print and choose FireMenu Print Server (not “Standard print”)—drawer open from the POS works in this mode.
On the Sunmi printer row that has the drawer physically connected, turn on Cash drawer. If you have several printers, enable the drawer on only the one that actually drives that cable.
Click Save changes, then Save settings as default so the venue keeps the configuration.

Opening the drawer from the POS

After saving, the payment screen shows a Cash drawer button—tap it when you need to give change or deposit cash without a manual key. If the button is missing, recheck the steps above (FireMenu Print Server and the printer toggle).

Auto-open after payment

To open the drawer automatically after a successful payment:

Open Settings → General tab.
Under Automation, enable Automatically open cash drawer when order is paid.
Save the page the same way you save other fields there.

This fits workflows where cash always goes straight into the drawer after each sale.

Common issues

POS button exists but nothing moves—check the cable to the printer, drawer power if applicable, and whether the printer IP changed on the network; see your printer setup article.
No Cash drawer button—FireMenu Print Server is not selected, no printer has Cash drawer on, or changes were not saved as default for the venue.
Two printers marked for the drawer—only one printer is used for drawer commands; keep a single printer flagged to avoid confusion.

Printer setup—network, Chrome on the terminal, and FireMenu Print Server.
POS shifts—when the drawer is used during a shift.
Wallets—cash accounting alongside register discipline.
