You're partially correct when you say JetDirect will only handle one connection at a time. In fact, it will only handle one lpd (port 515) connection at a time. It seems that HPs JetAdmin software uses an SNMP connection to the printer to get status while a print job is active. I imagine this is to avoid the overhead necessary to maintain multiple active connections. I also suspect it creates a little more demand for JetAdmin software :) ---Steve
