Ladies and gentlemen, I need your help.<br />I will be using a Dell Inspiron 4000 laptop computer in a new business venture. It has a very loose USB port for the printer (that if bumped slightly, causes the printer to not be recognized, it's a hassle). And I will be using this laptop in both my car and in the office. So in order to get around that, I have been told that a "port replicator" or a "docking port" is the way to go. Now I am not totally computer illiterate, but in my search of E-Bay, it seems that I found these items for all but the 4000. So is there a specific model of port replicator I should be looking for? Is there one place that I can tell what replicator my machine will need? And if not, how do I tell what ones on E-Bay may work, without reading the whole description. I have netzero dial up, and that takes a long time. (or is there an "easy" way to fix the USB port?)Any and all suggestions will be appreciated.
