After upgrading to Debian 11 the HP AIO scanner took very long to be detected and sometimes it did not work.

1. install these packages

   apt-get install hp-ppd hplip hplip-data libhpmud0 sane
   

2. reinstall libsane-hpaio as suggested by reference 1

   apt --reinstall install libsane-hpaio
   

3. comment all backends in /etc/sane.d/dll.conf

4. you should have a file in the SANE configuration, like this

   /etc/sane.d/dll.d/hplip

   # dll.conf snippet for hplip
   #
   
   hpaio
   

5. check if scanimage detects the scanner in a matter of seconds

   scanimage -L
   

6. check if remote scanning still works
