The Hiera variable cups::printers has been added to allow end users to define their printers in hiera and require no additional puppet manifest code than 'include cups'. However by not including a default option the puppet manifest will fail if the user does not specify cups::printer in Hiera. This change will add a blank hash to the hiera_hash call so that if it returns nothing then no error is logged and no printers created
