Under Loki, my HP LaserJet 1012 connected and worked without any setup or issues but under Juno it doesn't seem to want to connect. Any ideas on how to get it working? I tried the add a printer button but it didn't seem to want to work afterwards.
I just reinstalled the laptop from Loki to Juno...
I got the problem with that my phone is not charging anymore when i will connect the cable to the laptop.
What happens - i will connect the phone to the usb, phone will show charging, juno will show the accessible device in device-list of files, ...and in one second phone is disconnected from power and stop charging. When i will click in device list to open this phone, it will "mount" the phone even if the phone is selected to "charging mode" and in that moment phone is charging again.
I think it is the same issue with your printer.
Probably Juno will try to read-up the connected device for a second and after that it is turning off the powersupply to device... :/
I found a fix. I manually added the printer using the + button on the printer menu in Settings and finding it in the list, then enabled it and set it as default. Then I opened the terminal and used lpq to configure it.
The commands I used are:
Then I was able to print from LibreOffice without issues.
