Print fails Lubuntu 20.04

Asked by Stephen on 2020-06-08

I cannot get HP Deskjet 3720 printing to work since I upgraded to Linux Lubuntu 20.04 (from 19.04 where printing was fine).

HPLIP-gui (installed from Muon package mgr)
and/or HPLIP-toolbox (installed from which seemed to complete ok even though it failed to install some dependencies (but only after I had installed some of these manually).

Printing still works ok in LUB19.04 +in Windows10 (dual-boot)

All on same desktop pc.

Is there a known bug with Linux (L)Ubuntu 20.04, stopping HP deskjet3720 printing? (via HPLIP)?

Any workaround? - other than my own dual-boot as above. OR fix planned soon?

Thx from 3rdRockGuy Stephen (UK)

I imagine we could debug this by knowing where you came from and
what you have ended up with. However, it is a lot easier (for me) to ask
you to put the 3720 on the network with a wireless connection and give
the output of 'driverless'.

Snds like a good idea, Brian, ***except I have not got wireless on my Lubuntu 20.04 pc (I think) - or at least only ever used wired on it. ***How can I check if wireless is pos? - on this pc, in Lubuntu 20.04.

Windows 10 on same PC (dual-boot) shows:
1) Services: WLAN auto-config +WI-FI Direct Services = both enabled and running.
2) Device Mgr - Network Adapters =
"Intel... Network connection"
"Microsoft... kernel... adapter"
+ 8x "WAN..."
***3) But Network adapters =shows only wired

The 3720 has a wireless facility. I assume your router has too. Connect printer
and router wirelessly. The computer can communicate with the router and hence
with the printer.

ooo! I didn't know you could do that. Will try (as soon as I find out how to do it).
Watch this space...

PS How do I send you an attachment?
