Hi Robert,
Thank you for writing to Microsoft Community Forums.
I understand that you are facing issues with using printer, as it is not getting detected by the PC when connected via USB.
Upon checking the Brother website, I found that the drivers are integrated in Windows 10 for the model of the printer that you are using. One of the things that you can try is re-installing the printer drivers and check if you are able to use the printer. Refer the section Download and install the driver from the printer manufacturer’s website and sub-section What to do if the driver doesn't install from the article How to install the latest driver for your printer
In addition, you may want to refer the article Fix printer connection and printing problems in Windows 10
You can also refer the article Install the built-in drivers (For Windows 8 or later)
Let us know how it goes.
