cups-browsed doesn't automatically detect all printers in LAN without BrowsePoll about cups-filters

[tillkamppeter]

For cups-browsed to discover the remote CUPS queues in the same local network, it is enough to have a line

BrowseRemoteProtocols dnssd

in /etc/cups/cups-browsed.conf.
For discovering IPP network printers you need to set one of the following:

CreateIPPPrinterQueues No
CreateIPPPrinterQueues LocalOnly
CreateIPPPrinterQueues Everywhere
CreateIPPPrinterQueues AppleRaster
CreateIPPPrinterQueues Everywhere AppleRaster
CreateIPPPrinterQueues Driverless
CreateIPPPrinterQueues All

Please check your cups-browsed.conf, or simply attach it.

And for USB printers: Conventional USB printers are not discovered and set up by cups-browsed. For IPP-over-USB printers you have to install ippusbxd and follow the instructions in its README.md file, especially apply the Avahi patch.

I have mostly default cups-browsed.conf for 1.16.1 version, I have only:

BrowseRemoteProtocols dnssd cups
LocalQueueNamingRemoteCUPS RemoteName

because remote cups is 1.4.3. But I cannot see printer created even by cups-2.2.5 with debug log:

cups-browsed[13107]: Thu Dec 14 17:09:49 2017 Avahi Resolver: Service 'test-pro-f27 @ linux-2' of type '_ipp._tcp' in domain 'local' skipped, not a local service

[tillkamppeter]

Please run the command

avahi-browse -v -t -r --all

and post its output here. Thanks.

Not sure if also this report is related:
https://forum.manjaro.org/t/printer-quit-today-after-updating/36610
I have enabled
CreateIPPPrinterQueues All
and modify avahi service to do the job ..

[tillkamppeter]

Try putting a line

CreateIPPPrinterQueues All

in cups-browsed.conf and make sure not having any of

CreateIPPPrinterQueues No
CreateIPPPrinterQueues LocalOnly

@zdohnal, @Ste74, anyone of you still suffers this problem? Could you please try with the newest version of cups-filters?
I am closing this now, please re-open if you still have this problem.

[zdohnal]

I'll check with others on the bugzilla ticket - if they still can reproduce the issue, I'll reopen this one.
