I have had a issue that has been plaguing me the last few days where I was unable to update the printer drivers on a shared printer. With the error message “Printer settings could not be saved. This operation is not supported.” After a bunch of searching I found that if you unable to change the printer drivers on a Windows Server 2012/R2 Server you need to first untick the share option on the printer. The change the drivers for the printer. After which you can re-share the printer on the network / directory.
