George, that is the hal ID for your adapter cable.. that is what I put into the URI field for the "other" printer and it forced my HP4 to lock in..no problems dropping since. If your problem returns you might try that but if it's working now I'd let sleeping dogs lie. Could be some cables are weaker than others (electrically not as well shielded maybe? and some just fail at some point. All's well thst ends.. Bill. george whitmore
