Salutations,
We have a MacOS print server with Papercut that is broadcasting in a feedback loop. We have about 20 printers on the print server which are shared via mac’s integrated “Share this printer on the network” option, (Papercut is just a database), which usually would share the printer via bonjour, named something akin to “OfficePrinter @ printserver” as we view it from another Macs add printer option.
What we are experiencing is a duplication (sometimes into the hundreds) of copies being broadcasted (see screenshot).
We have tried rebooting, re-adding printers, resetting the printing system, toggling sharing using both the system settings printer option and the sharing settings options. Both hide the printer, but the duplicates remain on the network for a time after. The add printer interface shows the many duplicates “Kind” as Bonjour, our legitimate printers appear as “Bonjour Shared”, I’m not sure if that plays a part somehow.
Our users have been adding printers from this menu since the beginning, and now every time the server reboots those printers added are no longer valid and show not connected. If we reboot the server and our user adds the printer right away after it’s back up, everything seems to “stick” and they can use it between server reboots. We thought it could be a network loop, but we can’t seem to find one in our network at all, so we are trying to explore other possibilities. Some of the other strange things are that the Locations of the duplicate printers often say the location, and a random computer in our domain, like “Office300 (room200pc.local)“. This is sometimes even deeper like “Office300 (room200pc.local) (404labmachine.local)”..
The server has two interfaces, one to a network with all of our users who print via their devices on the wireless, and one to all of our physical permanent machines(labs). Each printer is added to the server using IP on LPD protocol. Bonjour is turned off on most/all of our printers.
Any help or suggestions would be greatly appreciated! Thanks,
