Hi,
TL;DR:
I can pair my bluetooth printer but it fails to connect:
$ bluetoothctl connect DC:0D:30:90:23:C7
Attempting to connect to DC:0D:30:90:23:C7
[CHG] Device DC:0D:30:90:23:C7 Connected: yes
[CHG] Device DC:0D:30:90:23:C7 ServicesResolved: yes
Failed to connect: org.bluez.Error.NotAvailable
What do I need to add to my system to have this working?

I cannot connect my bluetooth printer using "bluetoothctl connect" (I'm

If I use hcitool/rfcomm I can send data to the printer. It works fine in
this case.
$ hcitool scan
