Is one more efficent than the other?
i don't know about efficiency, buy port 9100 is a direct socket into the print engine, ergo, it doesn't get put into another queuing system like lpd -- and it doesn't require any protocol handler like smb (and associated authentication).
Port 9100 is bi-directional. For example, with PostScript or PJL, when commands sent to the printer generate output it can be read from the network socket by your server.
Also, on HP printers, port 9100 is not subject to the annoying "header page" feature of HP's lpr protocol.
Anybody have any experience with IPP?
