Q: Server 5.1.5 Shared Printing No Longer Works w/ 10.11.5

Upgraded our servers over the weekend to 10.11.5 with the newest version of Server.  Shared printing no longer works.  This is the error message in the CUPS log: "Unable to encrypt connection: User interaction is not allowed."

 

Clients can add the shared printers but cannot print to them.  Print queues on clients say: "the printer is not responding"

 

Any solutions?

    I am sorry if a notification about this issue gets your hopes up, but I am experiencing the same issue with a freshly deployed 10.11.6 Mac mini with Server 5.1.7.

     

    Any printer/copier I setup and share with CUPS 2.1.0 will happily negotiate and add to any deployed device with the same driver version.

     

    The devices are a mix of OS X 10.9.x-10.11.x but every print job will stall with "The printer is not responding." a split second after "Connecting to printer."

     

    Did you find your way out of your issue?

     

    I would greatly appreciate an update.

    Unfortunately, Apple Support did not provide a solution.  I ended up having to do a clean install and start over.

    Our shared HP LaserJet printers recently stopped working in exactly the same way you describe, i.e. "Not responding" message in the client's queue and the same CUPS log entry on the server. The printers are shared on a 10.11.6 system with Server.app 5.1.7. The shared printers had been working fine for months. I tried the following troubleshooting steps, in order, without success:

     

    • stopping and restarting "Printer Sharing"

    • stopping and restarting CUPS

    • un-sharing and re-sharing each printer in "Printers & Scanners"

    • restarting the entire server

    • deleting and re-creating the printers on both the server and the client

     

    One possible lead: In our case, the problem started on the same day we replaced our server's primary SSL certificate. I can't be certain that that's related, but since the CUPS error message mentions encryption, my current theory is that this has something to do with it.

     

    I still don't have a solution, so I've had to resort to reconfiguring all clients to print directly to the printers instead of queuing through the server.
