Hello @Luong Van Do (FHM.FCT)
Could you try the next? It seems that it doesn't catch your admin rights right way. Once this is not greyed out it should be easy.
Try to click "Change Properties" button on General tab, The printer properties box will close and will reopen with administrator privileges. Now click on the advanced tab and check if there is any change.
Otherwise I would recommend to reinstall updated driver pack for the printer from the manufacturer's website, as this may he grayed out due to a mixed or generic driver.
Hope it helps in your case!
Best regards,
