Screenshot of adding a new printer in system-config-printer

Screenshot of adding a new printer in system-config-printer

Did you follow the official documentation how to setup a network printer? You need the IP-adress of the printer and add it to the required input field:
https://doc.mageia.org/mcc/8/en/content/mcc-hardware.html#network_printer

I can add the printer manually by putting in the IP - but before it worked by automagically finding it on the network and offering it as a choice (this happens in Linux Mint and in Mageia 8) - I have two Cauldron installs which seem to work automatically - so when I choose "add printer" it scans a bit and offers my printer as advertised!!  When you click on "find a network printer" it should find one!!!  Linux Mint finds my printer automatically without me having to do anything!

I wondered from your screenshot whether you had clicked 'Internet Printing Protocol (ipp)' in the  'Find Network Printer' list. And if you do - what is the result?
I agree this is not 'automagic', but seems the logical thing to do with the dialogue presented.

If you look at the screenshot - there is a dropdown arrow on "Network Printer" and then again on "Fond Network Printer" - if I click on that arrow - the arrow rotates but nothing else happens (before it would search for a network device and display what it finds) - If i click on ipp or ipps, it asks me "Enter the device URI" . . .

Have you ensured shorewall isn't blocking the printer?

Quick way to ensure it isn't shorwall.
Add the following lines to /etc/shorewall/rules.drakx and restart shorwall ...
ACCEPT  net:10.0.0.0/8 fw
ACCEPT  net:169.254.0.0/16 fw
ACCEPT  net:172.16.0.0/12 fw
ACCEPT  net:192.168.0.0/16 fw

I thought of that and actually turned off the firewall using MCC and drakfirewall - "allow all - no firewall" using the GUI - I will try your suggestion but I thought shorewall is turned off when I do it through the GUI ?!?

I strongly dislike drakfirewall. Running it will remove anything it doesn't
recognize such as the lines in comment 6, so don't use it much, except when
testing new installations. I'm not sure whether it runs "shorewall stop" which
blocks all incoming connections, or if it runs "shorewall clear" which allows
all connections. Please either run "shorewall clear" which allows everyone
on the internet to connect to your compuer, or try comment 6 which allows all
traffic from withing your lan, no matter which subnet the network interface
is configured to use.

I tried both suggestions - but it didn't change anything.  I ran the "shorewall stop" command to completely eliminate the firewall - but system-config.printer still doesn't find any advertised printers - Same machine, same network - from Linux Mint it finds the printer . . .

Here's the output from the console:

See comment#8.  You need "shorewall clear" to completely shut down shorewall.  "stop" won't cut it.

I did both stop and clear - didn't seem to help ?!?  Maybe I should try a fresh install and see what happens . . .

Did a completely fresh install using Mageia 9 Alpha1 ISO - same behviour (out of the box) - no printer is found automatically - FYI

s-c-p has needed some love for a while now.  See https://bugs.mageia.org/show_bug.cgi?id=30398

Sad but true . . . but why does this work well in Linux Mint??  They also use s-c-p ?!?

Thank you Robert for all your lengthy trials.

This is clear enough; but this:

> I have two Cauldron installs which seem to work automatically - so when I 
> choose "add printer" it scans a bit and offers my printer as advertised!
> When you click on "find a network printer" it should find one
is confusing. Assume it repeats the not-shown problem.

This package has had various maintainers, so assigning this bug globally.

Summary: system-config-printer doesn't find a network printer (ipp or jetdirect) => system-config-printer doesn't find a network printer (ipp or jetdirect); used to work on M8.
