I'm having a tough time getting my Zebra 450 Thermal Printer set up on Windows 11. I can't seem to install the Zebra drivers from either the Seagull or UPS websites. When I try to install the printer, it doesn't show up in the list of available printers and instead gets recognized as an 'unspecified device' in the control panel. In Device Manager, it installs as a 'USB Printing Support (USB 3.0).'
Additionally, there are other Zebra printers on the network that I can't access. I think this has to do with my computer being on a private network while the others are on a domain. I've attempted various ways to switch my computer to a domain but haven't had any luck. Other machines on the network can see my device, but I can't access theirs.

You might want to try running the installer with your internet disabled. Sometimes, it can help avoid any network confusion. Also, check if the printer is listed under a different name, like UPS ZP450; I've seen it incorrectly identified as part of the LP 2844 series.
It looks like you're dealing with some network configuration issues. First, make sure you’re on the same physical network as the Zebra printers — being on a VLAN or a private network can cause this kind of problem. Since you mentioned all computers are connected to the same router, double-check any network settings that might separate your device from the others.
