The printer drivers are stored in C:WindowsSystem32DriverStoreFileRepository. I wouldn’t recommend manually removing any drivers, you can try to remove the driver from the Print Management console, go to Start and search for “Print Management” and open it.
Where are all drivers stored in Windows 10?

Where are printer drivers located on my computer?
If you do not have the disc, you can usually locate the drivers on the manufacturer’s website. Printer drivers are often found under “downloads” or “drivers” on your printer’s manufacturer website. Download the driver and then double click to run the driver file.
