SPM uses the LPR protocol if you specify it during port installation or reconfiguration. SPM deviates from the LPR standard in one way: it does not conform to the RFC 1179 requirement that the source TCP port lie between port 721 and port 731. This range is insufficient when a server sends data to more than 11 printers. SPM therefore uses ports from the general, unreserved pool of ports (ports 1024 and above). Better change those Bind local port settings to 1024-5000 HTH, Tom Thomas W Shinder, M.D., MCSE, MCT -----Original Message----- From: Thomas W.
