When printing a document (invoice or transport bill) in pdf format in Windows 10 a part of the text is being "encrypted" or deformed and letters are printed on each other. I have talked to the companies responsible for the documents and they cannot help me. The only help I have had is to use Window Edge instead of Firefox and with Edge the documents will be printed correctly. There must be a problem in the transfer between Firefox and pdf/Windows 10. The problem started during the Autumn of last year - probably after some updates.
