I have a friend who has a HP all-in-one printer. Every time he shuts down his computer or it goes to sleeps he loses the ability to print to the printer using a wireless connection. I can get it to work again by reinstalling the driver, but he then loses the ability the next time his computer is rebooted. He is using a laptop. I have checked his computer for malware and have not found any. He is using Norton anti-virus software. This only started happening the past three weeks, before that he did not have this problem. Does anyone have a clue as to what could be causing this?
