I have an HP Pavilion and an HP Photosmart C4160. Suddenly I can't print anything from the internet, word and excel are fine. I have checked the usb cable. I can't re-download IE8, the error message says my version is newer than IE site. I purchased a new wireless printer thinking the printer just quit ... not. The wireless won't communicate with my computer. Yes, the printer has a connection to the router. Any suggestions??
