Merge PDF files into 1 file

[snowseals]

Based on viewtopic.php?t=4913 I'd rather want to merge the 3 files into one PDF.
Is that possible with the "Merge files" option: https://robotask.com/help/merge-files.htm in the newer Robotask branch ?

I can save the docx as PDF using Word (or Acrobat's Print to PDF iirc).
Then I'd have 3 PDF files, that should be merged into 1, so I have 1 print-job in the end.
But how?

The idea is that this way, the sequence is always perfect and no other print-jobs can get in between.

You will just break your PDF files. Merge Files does simple "gluing" of files in a given sequence without taking into account file structure/format.
