Since you don't seem to share printers, try

disable spoolss = yes

Could be outfall of https://www.bleepingcomputer.com/news/s … -printing/

I hope this is not hijacking the post.

I am getting the same error. But unfortunately I need to share a cups printer. So I cannot disable printer sharing.

Is there any other fix to this problem?

Is https://paalijarvi.fi/tgblog/2020/05/25 … e-network/ an option?
(For POSIX systems you should™ be using cups anyway, no need to add MS' somethingsomethingnetwork protocol…)

Judging from MS panic-patches that boil down to disabling SPOOLSS I guess this is FUBAR (what to SMB is SNAFU ;-) and would look around for ways to share printers that do not use SMB.
Though there's no mention of this in samba's release notes or CVE history, so it could be a completely unrelated bug that you should report https://bugzilla.samba.org/
(In any event, failing to start samba because of the printing situation isn't an ideal way to cope w/ the issue ;-)

Thank you for replay i added all options from https://wiki.archlinux.org/title/Samba# … er_sharing and its working perfectly now. I don't know how it happened because i don't even have printer in house.

The SMB print service is active by default (it's a really horrible protocol…) - you don't need a printer for this and this is also not a problem with your configuration.
There's certainly a bug and my guess is that it's related to the fact that the SMB print service is basically an invitation to get your system hacked
Explicitly deacitvating the print service simply side-steps the bug.

Thank you, @seth.

The alternative (using cups directly) works for me.
