Following the answer below:
I was struggling to make that command,
AcroRd32.exe /t <filename> <printername> <drivername> <portname>, work with the latest version of Adobe Reader DC. The problem was that the files were not sent to the printer (I tried multiple variations of the command).
I found a solution by installing an older version of Adobe Reader, v9. However, I would like to use the latest version of Adobe Reader.
Isn't the print command working anymore in the new version of Adobe Reader or has the command changed?
PS: Foxit Reader, RawFilePrinter, SumatraPDF, 2Printer are not suitable for my needs.
