  So in the access-lists you create you are using a Type of 0. I guess to
specify
any type of sap. It doesn't work this way with using a 0. 0 refers to
unknown type
not any sap type. This could be one of the issues with the sap filter not
working.

  So I would change to

  IPX sap access list 1000
      permit FFFFFFFF 7 printer
      deny FFFFFFFF
