Dear Steve, I have appended an e-mail from the IBM TCP-L mailing list, authored by Les Geer of IBM, to this response. It explains which TCP ports are normally used by LPR clients when they are trying to send data from their machine to a remote host (in your case the ports the lpc daemon would probably query first to create an outbound transmission for you to the JetDirect card) . You should check to see whether some process has blocked the ports listed in the appended e-mail on your Linux partition so that the lpc daemon cannot find a local port to use to begin processing a request to send a file to a printer. You should also be able to find a descrition file (example it could be a *.ini file) regarding your lpc daemon service on your partition which will tell you how many ports in total it can query when trying to fulfill a print request and the local port ranges as well.
The LPD daemon on your Linux partition is used to receive files for printing from other hosts. Typically it will have no effect on problems with sending files from your Linux partition to a remote printer.
