Description Ondra Pelech 2011-06-20 21:28:48 UTC

To add a new printer, system-config-printer asks me to insert my password two times in a row.
(first to modify firewall settings, that to get list of aviable devices)

why doesn't it ask just onece?

Comment 1 Tim Waugh 2011-06-21 09:54:32 UTC

It's asking for different reasons.  The dialogs explain what each is for.

Having said that, it would be nice to "front-load" all the authentication, like the GNOME 3 system settings dialog does.

Comment 4 Ondra Pelech 2014-07-06 10:46:05 UTC

does not work

1) start system-config-printer
2) click Unlock and authenticate
3) click Add
4) click Network Printer
5) another authentication dialog appears
6) click Find Network Printer
7) click Find

this error appears (but system-config-printer continues to work, does not crash)

Caught non-fatal exception.  Traceback:
File "/usr/share/system-config-printer/probe_printer.py", line 255, in _do_find

    stderr=null)

Continuing anyway..

That's for firewalld, and the Unlock button can only be for one oforg.opensuse.cupspkhelper.mechanism.all-edit and org.fedoraproject.FirewallD1.*, not both.

The reason the gnome-control-center Printers panel doesn't show this dialog is... it doesn't touch the firewall at all.

I moved the Firewall-adjustment so that it only happens when Network Printer is expanded, *and* no network printers were found. Short of actually ripping out the firewall adjustment code, there's nothing else we can really do that I can think of.

That's harmless, and just means you don't have hplip installed.
