LibreOffice 6.1.5.2 - Problem with Prints to a Fax Printer

Hello.

I recently updated an old LibreOffice Installation from version 3.3.2 to version 6.1.5.2.

Problem is, that all after the update my document template isnt working anymore.
In my template there is a faxnumber which the document should be faxed to.
With LibreOffice 3.x these faxnumber was passed through the Fax Software (Actfax, Version 6.95) during a print to the Fax Printer. This isn´t working with LibreOffice 6.1.5.2. Someone told me, that LibreOffice in newer (actual) versions handles prints different than in version 3.x - it generates a picture during printing process, so that Actfax Software isnt able to read out the faxnumber from the document anymore.

Is there a way to change this / turn this off?

My Software Setup:
Windows Server 2012 R2
Actfax 6.95
LibreOffice 6.1.5.2

Thanks for ideas / help!
