I have not exactly the same problem but it is probably related. On Ubuntu 18.04.3, i choose Duplex "Long Edge" but it print a single- sided PDF document.. It was working on Ubuntu 16.04.x.. I tried Ubuntu 19.04 and it works too.
I use Evince for my PDF. If i choose another pdf reader like qpdfview it's works like expected. I tried lp command for testing and it's work: lp -d MP-2352 -o Duplex=DuplexNoTumble testfile.pdf I also tried to print a text document from gedit with Duplex "Long Edge" and it's not working. I got one side page. A document printed with LibreOffice works like expected. We use Ubuntu 18.04 on our company and is important to fix it because we are now unable to print PDF documents with two-side.. Thanks. Below some log: ...
