> python3 PDF_Report.py
> cp Report.pdf /opt/plcnext/projects/PCWE/Services/Ehmi/ehmi/

2. Call the script in the PLCnext Engineer program instead of executing the Python script.

3. Create a button in the eHMI and add the following action:

The pdf file opens now in your webbrowser. Printing is also available here.
