So, the situation was: a machine with existing home. A fresh install of 41.1 without using / installing any printer. An update with zypper dup (and only the standard opensuse repos of 42 activated and without having packman installed).
Ok.
That leads to a perfectly installed and working 42.2. But when you will try to install a printer (at least me) you get a surprise: The printer e.g. attached to usb is seen in lsusb. Is seen in CUPS (localhost:631 in the browser) and is seen in yast as expected. But listing the filters / printer drivers gives an entirely empty window.
Window? In what app?
So I did read through howtos and wikis and found a note about cups-browsing: with this updated system cups.browsing service is deactivated and not running. I found in the release notes the following: "The network printer discovery protocol has changed. The native method to discover network printers is now based on DNS Service discovery (DNS-SD, that is, via Avahi). The cups-browsed service from the cups-filters package can be used to bridge old and new protocols. Both cupsd and cups-browsed need to run to make "legacy" clients discover printers (that includes LibreOffice and KDE)."
Ah... rings a bell.
That is great information...only that I do not understand it. Does this mean: for discovering and registering the filter driver cups-browsing has to run always? Or can it be deactivated once the filter / printer is registered?
I think that once the printer is registered cups-browsed is not required. Unless there is a capability to find a printer that changes IP day to day via dhcp.
Where I am I don't have a printer, so I can't test.
DNS-SD is the same as DNS-m? I ask this, because before finding the trick with usb I tried to find the printer on the network. DNS-m was activated in the printer, IP was in the same subnet. Still Leap did not see any printer (firewall was stopped too). Now the printer Lexmark C543 is using postscript. Does this mean that in order to work out of the box, a network or otherwise printer has to be DNS-SD and PDF native compatible otherwise it is not seen anyway? Even if the printer offers DNS-m?
No, I don't think the printer needs to be pdf capable. Mine is not.
However, my network printer was never seen: I had to configure in YaST telling it the IP to test.
if he found his printer, "attached to usb is seen in lsusb", network is not relevant. yast may not "find"/identify his printer, but a simple matter to tell it to search for drivers for "XXXX" printer and add it to the system. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Photos: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 Photos: http://wahoo.no-ip.org/piwigo @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
