I am having an HP All-in-One 4255 with fax, phone, copy, scan and print facilties. I got it installed in Kodaikanal (TN) with that Phone No. Now I have moved to Hisar Haryana and I have new phone No. with which I have connected the machine. Now whenevr I printout any report of fax or caller ID, report displays old phone No. alongwith my name. Hoe exactly to change that old No. to the new one, please tell, as I am unable to do that with all my efforts and whatever little knowledge.
