So we found the issue. It was indeed the CAB .lbl file, but sadly it was not working with the changes you showed. However we found a different template for OpconPlus. After a few tries, it started working with the following setup: P0 (applicator controlled by PLC) and at the end, there should be an A [NOPRINT] (had to hide the code inbetween the 2): Still this solution only works with SD card. The IFFS memory still cannot be reached, it says "Mermory Card error". Maybe the FB cannot handle that. The FB's document should include more of the correct setup parameters from printer side, or at least hints in the error messages with the faulty lines. Right now it's really hard to do the troubleshooting like this. Thanks for the tip!
