-- Stub file PDPrinterRpcServerImpl.mesa was translated on 18-Nov-83
    -- 13:13:33 PST by Lupine of 18-Feb-83 11:25:52 PST.

-- Source interface PDPrinter came from file PDPrinter.bcd, which was
    -- created on 18-Nov-83 13:13:16 PST with version stamp 52#57#3264557214
    -- from source of 18-Nov-83 10:11:40 PST.

-- The RPC stub modules for PDPrinter are:
    -- PDPrinterRpcControl.mesa;
    -- PDPrinterRpcClientImpl.mesa;
    -- PDPrinterRpcBinderImpl.mesa;
    -- PDPrinterRpcServerImpl.mesa.

-- The parameters for this translation are:
    -- Target language = Mesa;
    -- Default parameter passing = VALUE;
    -- Deallocate server heap arguments = TRUE;
    -- Inline RpcServerImpl dispatcher stubs = TRUE;
    -- Maximum number of dynamic heap NEWs = 50, MDS NEWs = 50;
    -- Acceptable parameter protocols = VersionRange[1,1].
