Some printer drivers, even for Win8, are ONLY available via winupdate.
Sometimes there is no driver download,via winupdate only (so slow) and they will even state all this that printers support/driver webpage.
Most drivers that come from Windows Update are are also available via https://catalog.update.microsoft.com/v7/site/home.aspx which lets you download them for deployment or even import them into WSUS if required.
