As of now, the PDF conversion functionality is not available in the ootb version of the system.
Currently, we can recommend using the PDF conversion feature in MS Word by using the "Save As" option.
As a workaround, if it is necessary to prevent users from making changes to the PDF file after exporting:
You can upload a Word file with a password for modifications as a template for the printable. This way, the necessary data will be included in the file, but it will not be possible to make changes without knowing the password.
For what it's worth, I use Power Automate a lot to handle these kind of functions where Creatio lacks the functionality. You can handle the API response of Power Automate REST Trigger to give you the data back, etc...
If you are using 365 in your tech stack it, it could be an option.
