Help! Accidentally Updated Our Shared Printer Driver

Honestly, it might be worth asking your system administrator for some guidance here. They can provide clarity on this and make sense of the situation. You might also want to check out some resources on how print servers and driver deployment work.

If you have a remote management tool, you could deploy the old driver across the endpoints. That could save you from having to deal with the user permissions issue at the server directly.

Have you tried rolling back the driver to the previous version? It might be the easiest fix. Sometimes you can find that option in the driver settings on the print server.

Did you perhaps install the new driver over the old one instead of adding it as a new instance? If you added it, you could change it back through the printer settings on the server.

It sounds like you're dealing with a Type 3 driver, which means workstations are likely pulling the driver from the print server. I’d advise against just copying INF files to the server, as that can cause more problems. You usually don’t update the printer directly; you should be adding it as a printer port on the server and attaching it to the proper driver. If you have a backup, now is the time to use it!
