How to send sound through Bluetooth on Linux is excellent, helped me a lot. At the end are options for a pdf and print but they don't don't recognize I have already joined.
The print download is available to Howtoforge subscribers only. As far as I can see, you did not subscribe yet. https://www.howtoforge.com/subscription/
I did subscribe and paid 30 Euros. Then I logged on, found the tutorial which I had previously read after an internet search. Still couldn't print. The tutorial solved most of my problems, successful audio stream from pc to bluetooth speaker. Paired with my cellphone but can't maintain connection. I wanted to keep tutorial on file until I have solved this last issue.
Do you have printing set up in your browser? I have not in my browser on this workstation, and pressing the "print" icon at end of article just opens the contents in a new browser tab. Opening the PDF and then printing that should work.
I subscribed earlier today & I also cannot download the ispconfig manual etc. Seems to have not recognized I subscribed.
