Hi @AnthBraid, I've run into this in the past myself and it can be quite frustrating. However, it's normally not the Xerox driver that is doing this but Windows 10, an application on your PC, or if your PC is managed by an IT Helpdesk, they may be able to set your default printer through a system policy. Fortunately, in most cases, this is just a setting in Windows 10 that is designed to change the default printer to the last one used.
I suggest looking at this MS support article to see if it helps you with your issue. https://support.microsoft.com/en-us/windows/how-to-set-a-default-printer-in-windows-10-e10cf8b8-e596....
If this does not work, you should try to keep track of what happens prior to the default printer changing. This may help you figure out what is changing the default printer.
