Problems with AirPrint

1

Hi - I've only been using HA for a week or so - I set it up successfully to control my Tesla powerwall settings to stop it discharging when Octopus try and charge the car out of the normal schedule. That is working well.

However, I've been having problems with AirPrint - printers can't be found, go offline despite the fact that I can ping there IP address. After some pluggin and unplugging of cables, I finally found that the HA was the problem. I'm running on a Pi-4 and have it directly plugged into the router.

When I unplug HA, I can see the printers, but soon after reconnecting it, they disappear.

Any suggestions welcome - I can't see any similar problems on the message board, so I'm guessing this is not a common problem.

Thank you,

Colin

Is something in HA re-directing your DNS, like PiHole, AdGuard, or another program that messes up your DNS?

Thanks for the reply.

Not that I know of - I've installed Duck DNS, NGINX, Terminal and SSH, Tesla HTTP Proxy and via HACS, Octopus Energy and Tesla Integrations.

Thank you,

Colin

How is your network configured IP wise: are you using fixed & dynamic IP addresses at the same time?
Check if you don't have an IP address conflict.
Are you sure that those ping replies come from the host you think they are?

If HA is causing all this, without it also being responsible for your network through additional add-on or integration, it seems to me that you have another problem which goes further then your HA.
