Has anybody had success with printing from Collabora? I finally got it working but printing doesn’t work. I get a brief spinner animation that says “Downloading” in the middle or below it and then nothing happens.
Printing used to work, but I experience the same problem as you with latest Chrome version. Firefox offers PDF download. Until we find the solution, i.e. explore the latest innovations of browser developers, you can use File - Download as - PDF, it will be the same. Printing was basically downloading a PDF and sending it to the printer directly.
