I have an HP DV5 notebook (laptop) with Vista and an Epson CX5900 multi-function printer. After 13 months of working perfectly together the Epson now seems to interfere with the notebook. When using MSWord the number 6 prints infinitely and when using other programs such as Internet Explorer, Outlook etc they won't accept the mouse and keyboard commands unless the printer is disconnected.

Through a process of elimination I have determined that the printer is conflicting with the notebook but I don't know why.

The note book is 13 months old and the printer is about 18 months old.

Any ideas?
