Title:
HP Bluetooth Printer Pairs but Stays Disconnected
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have an HP Deskjet 460 with BT module. This printer was working via
Bluetooth in Ubuntu 16.04, but now fails to connect in Ubuntu 18.04.
In Ubuntu 16.04 I was able to use this doc to setup the printer:
https://help.ubuntu.com/community/BluetoothPrinterSetup. However,
this doc is now outdated for Ubuntu 18.04 since "hidd" is unavailable.
I've tried the info contained in these links to no avail:

* I did try to "update bluez to >=5.28.2"
* I did try to "restarting bluetooth service"
* I did not try "removing btusb module"
Further advice in the above links did not help.
In 18.04 I can remove the device using the Settings->Bluetooth UI.
Then the Deskjet 460 S/N XXXXXXX appears as "Not Set Up". Then I can
double-click on the device, and it briefly shows "Connected", then
"Disconnected". Now the device is in the Settings->Bluetooth UI, and
when I double click the device it shows "Connection Off", Paired Yes,
Type Printer, and the MAC address. I'm unable to change the
"Connection Off" setting via the UI.
From bluetoothctl:
