Daisy

Daisy is a Bulgarian manufacturer with two distinct firmware lines in the e-bon registry: Daisy (the BG-original line, covering eXpert SX, perfeKT, FX1200) and Daisy RO (Romanian-localized variants with RO firmware and ANAF certification). Both speak the isl (Information Systems Limited) family. For Romanian deployments, the RO variant is the right choice in nearly every case — it is the one carrying the ANAF certification — but the original BG entry is kept in the registry to support cross-border installations and merchants who imported hardware before the RO line existed.

At a glance

Choose a transport

Both Daisy variants accept TCP/IP over wired Ethernet, Bluetooth, and Serial (RS-232). USB-connected units go through a USB-to-Serial bridge (CDC-ACM or FTDI) and are addressed as Serial. Wi-Fi for the AMEF link is not supported; see the Wi-Fi note in Supported devices.

Use the connection defaults

Both protocols default to TCP port 9100 and 115200 baud — the standard ISL-family values. Override them only when the device has been re-configured locally or is reachable through a port-mapped NAT.

Pick the right firmware variant

Pick daisy-ro.isl for ANAF-certified Romanian deployments and daisy.isl only when the unit is running the original BG firmware. No other protocol-specific quirks are documented at this time; standard troubleshooting applies — see Troubleshooting.

Pair the printer

Daisy printers pair through the standard Android flow. Auto-detect will usually land on the correct variant, but if you are pairing a Romanian unit and the app suggests plain daisy.isl, re-run with daisy-ro.isl selected explicitly. The full walkthrough is in Pairing your fiscal printer.
