Automatic adding printer in hplip-3.20.9 & ubuntu

Asked by Dominique PAUL on 2020-10-09


In some circonstances, in setup process, a printer queue is automatically added.
In the page "Select From Discovered Devices", a fleeting popup indicate a printer is added, with the name "deskjet-2700-series" (my printer is "deskjet_2700").
After the process, there are 2 printers queues: the one I have added, and the unwanted. The unwanted printer is the default printer for the system.
The unwanted printer could be a model for the user (pre-completed form). But, I think, the printer adding must be under user control.

xubuntu 18.04 (LTS)
HP Deskjet 2700 series

The setup process takes place during running,
OR hp-setup command after removing the 2 printers queues by hp-setup -r.
If the unwanted printer queue is removed by system-config-printer, this queue is not recreated.

Steps to recreate the problems

- create a vbox; take care of usb filter
- install xubuntu 18.04 in the vbox
- verify usb
-- plug the printer, power on the printer
-- type "lsusb", the printer must be in the list

- uninstall the ubuntu hplip 3.17.10:
-- sudo apt-get purge hplip hplip-data hplip-doc hplip-gui hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs
-- sudo rm -rf /usr/share/hplip/
-- sudo apt-get autoremove

- download hplip 3.20.9, i.e.:
-- hplip-3.20.9-run
-- hplip-3.20.9-run.asc
put them in a temporary directory, and do the gpg verifications

- in a terminal, execute hplip-3.20.9-run
-- when there is a question in the terminal, accept (tape enter), including on "RESTART OR RE-PLUG IS REQUIRED"
-- during the setup process, in the page "Select From Discovered Devices", a fleeting popup indicate a printer is added, with the name "deskjet-2700-series".

- after running hplip-3.20.9-run
Launch system-config-printer (in the application menu (mouse head icon), in parameters, it can be called "Printers"). There are 2 printers queues instead of 1.

Where is described the driverless queue added by OS?
Why it be added if setup process executes during and not after?

Can you help with this problem?
