smb This backend sends print files to printers shared by a Windows host. Examples of CUPS device-URIs that may be used includes: smb://workgroup/server/printersharename smb://server/printersharename smb://username:password@workgroup/server/printersharename smb://username:password@server/printersharename The smb:// backend is a symlink to the Samba utility smbspool (does not ship with CUPS). If the symlink is not present in your CUPS backend directory, have your root user create it: ln -s 'which smbspool' /usr/lib/cups/backend/smb .
