In another partition that I keep for testing, I had made a clean installation of 20.04 and after installing hplip the same printer works without problems.

thank you for your bug report, what's the output of

$ ls -l /etc/cups/ppd/DeskJet-3630.ppd
$ ls -ld /etc/cups/ppd
$ ls -ld /etc/cups

the log suggests the ppd file is not accessible to the process

No one driver work

~$ ls -l /etc/cups/ppd/DeskJet-3630.ppd
ls: impossibile accedere a '/etc/cups/ppd/DeskJet-3630.ppd': File o directory non esistente

~$ ls -ld /etc/cups/ppd

Screen of Hplip

In the properties window of the printer connected as USB it indicates the absence of an HP file, on test printing with network installation the printer does not report an error, but does not connect.

Inattiva - Il file "/usr/lib/cups/backend/hp" non è disponibile: No such file or directory

Till, could you investigate the issue?

Is the hplip package installed on your system?

Please run the command

dpkg -l | grep hplip

and post the output here.

Also did you ever try to install HPLIP from the upstream site? Did you ever try to remove such an installation?

I did tests with both Hplip installed as .snap and command line and from upstream site.

~$ dpkg -l | grep hplip
ii hplip 3.20.3+dfsg0-2 amd64 HP Linux Printing and Imaging System (HPLIP)
ii hplip-data 3.20.3+dfsg0-2 all HP Linux Printing and Imaging - data files

How can I possibly remove that from the upstream site?

Where did you get a .snap from HPLIP?

From software center

It looks like the problem I've got since upgrade to 20.04. Had the permission warning to the ppd file as well, but tried to add user to lp group. Here's the current output of my hp-check:

Just to add more info, I tried the one from distribution repository and the upstream one with the same result

On the machine where you still have the problem could you remove your print queue and then unplug and re-plug the printer? Does a new print queue get automatically created?

What is the output of the following commands and post the output here:

lpstat -v
driverless
ps auxwww | grep ippusbxd

If a queue actually got auto-created for your printer, couls you attach the queue's PPD file from /etc/cups/ppd/ here?

You can remove the print queue (cancel the job) and then disconnect and reconnect the printer.
A new print queue is not automatically recreated.

Please

- Remove the .snap of HPLIP, it is experimental

- Remove any HPLIP version installed directly from HP

- Re-install Ubuntu's HPLIP via the command:

  sudo apt install --reinstall printer-driver-hpcups printer-driver-postscript-hp libsane-hpaio hplip-gui hplip hplip-data libhpmud0

  Please post the output of this command here.

- Remove your current print queues with the commands:

  lpadmin -x DeskJet_3630
  lpadmin -x HP_DeskJet_3630_series

- Unplug the printer from USB and re-plug it. Does a new print queue get created ("lpstat -v" should show it)? Can you print using this queue?

- Could you create a driverless print queue (this queue does not use HPLIP but common, manufacturer-independent communication protocols of the printer)? Use the command

  lpadmin -p DJ3630 -E -v ipp://HP%20DeskJet%203630%20series%20%5B9B20BB%5D._ipp._tcp.local/ -m everywhere

  Can you print with this print queue?

It seems to me that in this discussion from the Ubuntu Mate forum there is a similar problem:
https://ubuntu-mate.community/t/hplip-missing-files/21782

Stefano, thanks for the Mate forum link, I have tried to make up the sum of the tips to help users get HPLIP working again.

So anyone here, please try to clean up any HPLIP mess on your system using the following steps:

1. Remove HPLIP deb-packages

sudo dpkg -P --force-depends hplip hplip-data hplip-doc hplip-gui \
libsane-hpaio printer-driver-hpcups printer-driver-hpijs printer-driver-postscript-hp \
hpijs-ppds libhpmud0

2. Remove upstream-installed HPLIP using HPLIP binary uninstaller

wget https://nchc.dl.sourceforge.net/project/hplip/hplip/3.20.3/hplip-3.20.3.run
sh hplip-3.20.3.run --noexec
cd hplip-3.20.3
sudo python3 ./uninstall.py
sudo rm -rf /usr/share/hplip/

3. Reinstall deb-packages with:

sudo apt install -f hplip-gui printer-driver-hpcups printer-driver-postscript-hp libsane-hpaio

Then try to create a print queue with hp-setup and, if needed load the proprietary plugin with hp-plugin. Also printer setup with GNOME Control Center or system-config-printer should work again.

DO NOT install printer-driver-hpijs and hpijs-ppds. These packages are deprecated and not maintained any more, and they also have no benefit compared to printer-driver-hpcups.

The printer still does not work.

Ubuntu 20.04 needs
- either the HPLIP version 3.20.3+dfsg0-2 packages from the Ubuntu repositories
- or HPLIP version 3.20.5 (or higher) from the HPLIP pages

Version 3.20.3 from the HPLIP pages does not work.

I tried reinstalling from hplip-3.20.5.run, I am attaching the errors in the attached images.

I managed to get my printer back to work in 20.04 by installing hplip from ubuntu repo (3.20.3+dfsg0-2), and then following this hint to install the hp-plugin:

I had to type "cont" and press return after the depicted command to start the process.

I tried to follow the proposed advice, but the installation process loops.

I believe this bug affects me, also, but I have a different printer, and I get a different message. I have posted my issue here:

It might be that the same bug affected me after upgrading to 20.04 with another printer: https://answers.launchpad.net/hplip/+question/690767

I also recently tried hplip 3.20.6 for a freshly installed xubuntu, but it did not help. (the result of hp-check brought the same result as https://answers.launchpad.net/hplip/+question/690767 (#5). I was forced to downgrade the system again because it is essential to keep the printer functional.

After sudo apt purge ippusbxd and rebooting, I was able to print and scan with HP Deskjet 3639

I have similar problems. See: https://answers.launchpad.net/hplip/+question/692399

Is this entire issue due to a problem with folder permissions preventing an application or driver from accessing needed folders or files?

Please respond.

Did confirm the print doctor warning.

Some of the files it is trying to access are in fact locked.

Do not know why or if this makes any difference for actually using the printer or scanner.

Kindest regards; Scorch.

The bug is present for 3 different HP printers ,
via Wifi or via USB

It worked nicely , and began to fail maybe one month ago (near february / march 2021)

I guess some upgrade messed-up the printers.
