@mr-jones No actual GPO on the domain.
@dbeato Ah. Thanks. Yeah I isolated it to any printer mapping GPO.

Could it be that one (or more) of the machines that are picking up this policy are also configured to publish / share their printers and the other machines are configured to automatically map locally shared devices? Just spit-balling, but this sounds like one of those situations where there are actually a couple of issues combining instead of just 1 simple problem.
I've simultaneously deleted every printer from every machine in the OU. I've even tried stopping the print spooler on all machines in the OU, but updating policy with any printer deployment GPO still brings them back. With that being said, unless there is a better way to check, I don't think it's another machine publishing it. I do however think that you are correct about it being a combined issue, but I'm running out of ideas to troubleshoot this.
I did notice that under the registry path HKLM\System\CurrentControlSet\Control\Print\Printers there are like 8 extra OneNote printers listed. After cross-referencing them with
PS>Get-Printer | fl Name, PortNameand deleting the extras, they also all come back with a policy update, but are never listed in Printers & Scanners or Devices and Printers. Maybe it's related? -
OK, so it sounds like it's back to basics time:
- Multiple networks / segments or all on a common network
- use something like advanced IP scanner to see if there's anything unknown on the network it's self
- Keep in mind that printer sharing / publishing also has smb / samba in the loop, not just the print-spooler
Where I'm going with this is that there could be something publishing on the network with upnp or, zero-conf, bonjour or some other automagic protocol that your endpoints are only picking up based on one of the options (or defaults) in the GPO. The other thing to check (if not already done) is the protocols and services that are enabled on the printers themselves. Best thing is to disable all of the ones that you aren't using like bonjour, air-print, etc etc

Thanks. I'm going to take a break from this until tomorrow. But you've given me a few options. I appreciate it.

I think so, he mentions "Classroom Xerox" in an earlier post

Yes, we have 11 of them.

@mr-jones Xerox has a feature called WSD that allows for Windows to discover printers, sometimes automatically. Try disabling WSD on the xerox to see if that alleviates the issue (we disable it on all ours)

All printers has WSD. It is horrid

I had to double check, but it's turned off on all.
