HP Port Resolver

part of hp printer files
Ɯbermittelt daten an HP
It is certainly part of the sofware used to drive an hp color laserjet. Sometimes when it "has encounterd a problem and needs to close" no further diffuculty emerges. At other times memory error messages appear, sumtimes followed by abrubt application failures. HP seems to know little about why this problem occurs.

too many files in task manager and not deletable
Replicates itself with each print job eventually forcing me to reboot to clear all of the instances.

HP product AKA "A useless background program that eats up RAM." My advice, get rid of it.
It has brought my server to it's knees on more than one occasion
