Description of problem: I cannot use my remote Samsung Laser at home Version-Release number of selected component (if applicable): cups-1.7.1-8.fc20.x86_64 How reproducible: always Steps to Reproduce: 1.try to discover and install on my laptop a printer that is connected to my desktop 2.printer is not autodiscovered, i.e. it should be in the list automatically 3.when printer is discovered as a network printer in the selection list it it searched as remote CUPS printer connected via DNS-SD, but when I apply I get CUPS server error: destination socket is not connected Actual results: no installation of remote printer Expected results: installation of remote printer (it was working on F-19) Additional info: printer is fine when used locally
the correct message is: CUPS server error There was an error during the CUPS operation: 'Il socket di destinazione non è connesso'. (destination socket not connected)

Created attachment 885947 [details] debug file -troubleshooter funny, as I could install the printer by using cups admin tool, and printer was discovered fine.But I had no success in printing test file, see attachment. Anyway I still get same error if I delete/reinstall printer in system-config-printer

Have I understood correctly? > 3.when printer is discovered as a network printer in the selection list it > it searched as remote CUPS printer connected via DNS-SD, but when I apply I > get CUPS server error: destination socket is not connected Can you explain what you are doing in this step? What application do you start, which buttons do you press, etc?
No, I mean that I assume that also on the remote computer I should see the printer in the available printer list,it doesn't happen maybe due to the type of printer. Then I tried to add a printer with system-config-printer,printer is discovered attached to 192.168.1.3 that is the correct IP of the computer where printer is connected. Then I get the error of destination socket not connected... Then I disisnstalled the printer on the remote computer then I tried to reinstall by CUPS administration tool,printer was discovered and installed, but no way of printing, it says that is not connected!!! Firewalld is in home zone on both computer (anyway it was working as a charm in F19): only difference is that I am using a new laptop with a fresh F20, while on the desktop I am using a F20 updated from F19.

Can you explain what you mean by "the available printer list" in terms of what actions you perform, and what results you expect? Please be precise -- it really helps when trying to narrow down this sort of problem.
I assume (but I am not sure) that also on the remote computer I should see the printer in system-config-printer tool (the icon of the available printer). That in my case is not true I am using 1.4.4 system-config-printer
Ah, no, it won't show up there. This is a change from how things used to work. Previously, cupsd would keep track of discovered print queues on the network. Now, however, applications discover network print queues when presenting the 'Print' dialog. A notable exception is that Firefox won't do this currently, owing to the fact that it still uses gtk2 and not gtk3 yet. Perhaps you could verify that e.g. gedit's print dialog shows the printer? On to the other part: the error from cups, shown by system-config-printer. Could you please run 'system-config-printer --debug &>output' and attach the output? Thanks.

Did you try adding a queue during that run of system-config-printer? It just looks like it started and then was closed.
not clear to me what is the meaning of adding a queue...if i cannot see the printer in the list. What am I missing?
Created attachment 886556 [details] system-config-printer -debug printer when adding a queue Hope that adding a queue means try to add the printer from system-config-printer
I'm trying to diagnose step 3 of your original 'how to reproduce' instructions. Were you not using system-config-printer to do that?
I was using system-config-printer as it was not discovered automatically (I am sure that I could print from remote computer in F19, F18 and previous releases) So I opened system-config-printer, I got the printer in Network printers (that was correctly shown as connected to my desktop only by IP) and I added it there.Then I got the error in socket connection. Hope it can help
So, can you do what you were doing in step 3, but using the --debug parameter to system-config-printer?
Created attachment 886935 [details] debug during manually adding a queue this is the full listing, at the end I got the usual message of Cups socket disconnected
no improvement also with cups from updates-testing
I made a test, I disabled the share option on the printer, and also I disabled the option to publish shared printers on the network. Then I re-enabled both options and I was asked to allow adjustment of firewall rules!!! now everything works, not clear why operator is asked twice for root password anytime he wants to apply any change.Furthermore,it is not clear why in Centos I can print any document on the shared printer but test page print is greyed in system-config-printer
an additional comment: I am not sure that in the meantime I changed the default zone in firewalld, but I suppose that any adjustment should follow any change.
(In reply to antonio montagnani from comment #19) > now everything works, not clear why operator is asked > twice for root password anytime he wants to apply any change. This is because of the way PolicyKit works: access is granted on a fine-grained basis. There is an open bug tracking changing this: bug #714820. > Furthermore,it > is not clear why in Centos I can print any document on the shared printer > but test page print is greyed in system-config-printer It gets greyed out if the queue doesn't accept PostScript, or is not enabled, or is rejecting jobs.
I think the cause of this is that the printer is discoverable but its PPD cannot be fetched. I've fixed this upstream in commit 755a800.
I am having similar problems with my Samsung CLP-310 under fedora 21. Used to work. The computer sees it, installs it (using a CLP-350 driver; it used to use the 310, but it is no longer listed.) When I try to print a test page, the printer lights blinks for a bit, then nothing. The computer says it sent the test page, and it is now idle. It really sucks since it used to work fine. john
if you refer to a shared printer, you have to enable ipp and ipp-client on the computer sharing the printer
Closing this as the fix went into 1.4.6 (FEDORA-2014-13184). John: your problem sounds different to this one. Please file a separate report.
