IPP version incompatibility

[iagosansouza]

The problem

I am trying to connect to an OKI C711 printer via IPP but when creating the connection I get the error "IPP version not supported by the printer". I tried to find something about the IPP version of my printer and Home Assistant but found nothing.

Hey there @ctalkington, mind taking a look at this issue as it has been labeled with an integration (ipp) you are listed as a code owner for? Thanks!

Code owner commands

Code owners of `ipp` can trigger bot actions by commenting: - `@home-assistant close` Closes the issue. - `@home-assistant rename Awesome new title` Renames the issue. - `@home-assistant reopen` Reopen the issue. - `@home-assistant unassign ipp` Removes the current integration label and assignees on the issue, add the integration domain after the command.

same issue, following

as of 2023.6.0 ipp no longer connects to printer

I had the same problem. Adding the printer (Epson ET-3850) again with the option "Uses an SSL certificate" solved the problem for me.

I tried here but the same error happens

[ELKER54]

I managed to get it working by updating (I use the dock version) and removing and re adding the integration.

[ctalkington]

I'm hoping to expand support but it takes samples of ipp output to use as test fixtures.

right now the best way is to clone pyipp repo and run the debug example and submit that via issue.

Same issue for Oki C301 since upgrade

Same Issue with OKI B401dn: IPP-Version wird vom Drucker nicht unterstützt. Home Assistant version 2023.11.3

Same issue with OKI C822

HA core 2023.11.3

[LorbusChris]

@ctalkington I've changed debug.py to try to connect with my OKI C822 at ipp://192.168.1.73:631/ipp, but it doesn't yield anything noteworthy:

⬢[lorbus@toolbox examples]$ python debug.py 
/var/home/lorbus/code/python-ipp/examples/debug.py:50: DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()

ipp://192.168.1.73:631/ipp/print yields a 404:

⬢[lorbus@toolbox examples]$ python debug.py 
/var/home/lorbus/code/python-ipp/examples/debug.py:50: DeprecationWarning: There is no current event loop

And ipps://192.168.1.73:631/ipp yields an SSL error (as expected):

This is still an issue. @frenck mind reopening https://github.com/home-assistant/core/pull/115661 so I can work on this further there, otherwise I'll create a new PR.

Still an issue for OKI B401 ...
