Thanks.

The HP Laser 135ag is USB-only and Debian 11 is capable of setting it up
automatically if it understand the IPP-over-USB protocol. Can we first
test if it does?

Please give

  lsusb -v | grep -A 3 bInterfaceClass.*7

Hi, thanks for answer.

This indicates that the Laser 135ag understands the IPP-over-USB protocol.
'systemctl show ipp-usb' should show the uni as active. See sections 14,
15 and 16 at

  https://wiki.debian.org/CUPSDriverlessPrinting

Give what you get for the command

  driverless

'systemctl show ipp-usb' should be 'systemctl status ipp-usb'.

Hi,

driverless say...:
ERROR: ippfind (PID 21661) stopped with status 1!

jannid@janni-aspirea51551g:~$ systemctl list-units "ipp-usb*" | grep service
  ipp-usb.service loaded active running Daemon for IPP over USB printer support

jannid@janni-aspirea51551g:~$ systemctl status ipp-usb
● ipp-usb.service - Daemon for IPP over USB printer support

I hope, that is correct so, my english is not so good....

ipp-usb.service is active when the printer is connected to USB.
That is good.

Give the output of

  avahi-browse -rt _ipp._tcp

avahi-browse is in the avahi-utils package. Install it with

  apt install avahi-utils

Hi Brian_P,

The device works, namely the printer, as well as the scanner! I discovered on the net, that the printer MFC 135ag is not an HP, it's a Samsung. HPlip is therefore completely useless for this device. You need to persuade this devive to run, the so-called Samsung ULD drivers. Name of the driver is: HP Laserjet 1300 pcl3.

Many, many thanks for your efforts.
I hope my English is understandable so far...;-)
Best greetings from Braunschweig....
