If the internet is working at the venue but the fiscal printer appears in red, there is a local communication issue between the POS application and the fiscal printer.
Verification steps:
1. Turn the fiscal printer off and back on. Make sure:
Datecs is in PC Connection mode
Partner is in Operator 1 mode
2. Check the physical connection: the fiscal printer must be connected to the router via network cable, the POS tablet must be connected to the same Wi-Fi network as the router (NOT to a mobile hotspot — see below)
3. Reinstall the fiscal printer:
Go to POS Menu → Printers & Peripherals (Devices- Ebriza POS NEXT) → Press and hold for 2 seconds on the red fiscal printer to delete it → Press “+”, select the model, and wait for it to be automatically detected on the network → Select the detected fiscal printer and save
How to find the fiscal printer IP address:
Partner (when “OPERATOR 1” appears on screen): press the C.I.F / X button
Datecs: press ON → navigate with arrows to 5 - AMEF Info Report → TOTAL → 6 - AMEF Summary Info → TOTAL → ON → then press 6 (PC CONNECTION)
Why it does not work on hotspot- Ebriza POS works over a local network — the POS tablet and the fiscal printer must be connected to the same router.
A mobile phone hotspot does not allow this type of local communication between devices, even if the internet itself works.
Fiscal receipts are issued offline (internet is not required), but the communication between POS ↔ fiscal printer must happen through the local network.
Valid only for Datecs cash registers- If you encounter error 109986 or the receipt is not printing on the Datecs cash register, the issue usually occurs because the device is not set to the correct communication mode.
Turn off the cash register using the power button and restart it, then make sure to set it to “PC Connection” mode by pressing ON → 6. After this step, check if the receipt prints correctly.
Frequently asked questions:
Q: I get a "forbidden function" error when printing receipts. What should I check?
The main cause is usually a low/empty battery on the cash register — check whether the low-battery symbol appears on the register's screen. Quick fixes:
Restart the cash register (the C button for Partner).
Check the printer: POS Menu → Printers & Peripherals and see whether the cash register appears in red (disconnected).
Delete and re-add the printer: press and hold the printer for 2 seconds to delete it, then add it again using the "+" button.
Edge cases
After a power outage the printers stop working (neither the fiscal nor the non-fiscal one)
After a power cut, printers may change their IP addresses on the network, so the POS can no longer find them. The fix is to delete and re-add them:
POS Menu → Printers & Peripherals (in Ebriza POS NEXT: Devices → Printers & Peripherals).
Press and hold for 2 seconds on the printer → Remove.
Press "+" (in Ebriza POS NEXT: "Add peripheral"), select the model and let the app detect it on the network, then save.
