However, the fix is really simple just go back to the General tab

and click Change Properties in the bottom left corner. The printer properties box will close and will reopen with administrator privileges. Now click on the advanced or port tab and you will be able to make changes since it opened the dialogue box with administrator privileges.

Note: If you are trying to change the properties on a printer that was shared from another computer, this isn’t possible. You need to go to the computer that the printer was shared from to be able to change the properties.

I hope this helps. This was posted by techspeeder
