Description Johannes Meixner 2013-03-07 15:49:04 UTC
The YaST printer module shows user info when it seems
a firewall is active for printing in the network setup
and for print queue sharing setup.

But the YaST printer module currently does not show
user info when it seems a firewall is active when
a printer device is set up that is connected via network.

For the automated printer setup during installation
no popup should be shown but in this case the
proposal text may contain additional information
if a firewall is active.

When a network printer should be set up
but a firewall is active it may happen that
the firewall blocks network printer autodetection
(e.g. some SNMP stuff might get blocked or whatever else).

When a network printer should be used
but a firewall is active it may happen that
the firewall blocks to send data to it
(e.g. some SNMP stuff might get blocked or whatever else).

In particular the "hp" backend for CUPS may require
some SNMP stuff or whatever kind of bidirectional stuff to work
(in addition to plain unidirectional TCP data sending to port 9100
on the printer device).

Also a "firewall is active" information could be shown
when after testpage printing the user clicked
"Testpage printing failed" for a printer that is
accessible via network (either directly connected
via network or accessible via a print server)
and when it seems a firewall is active.
