Printer auto-detection and scanning no longer works
Until recently, my up-to date testing KDE laptop would automatically show me
all available network printers under "Print System" and in the Printer
drop-down menu under File -> Print in KDE apps.
Lately, though, I must manually add any network printers. To use the "Scan"
feature of "Add Printer", I must change the subnet used from 127.0.0.* to,
say, 192.168.1* for it to succeed. This is a pain as I move around a lot.
My cupsd.conf has the line:
Browsing is on and BrowseAllow is set to All.
I've tried various other settings, each of which either renders CUPS
inoperable or makes the scan exhaustive within the 127.* subnet, but does not
restore the former automatic behaviour.
To be honest, I'm not sure how this is supposed to work.
Anyone else seen this or know how to fix it?
