I have a tablet laptop that I have never had a printer connected to. I used to email things to my husband or to office to be printed. I recently bought an Epson NX 400 printer/scanner/copier. When I use Windows XP -Add a printer function- I get the error Operation Could Not be Completed. I have the printer connected via USB port (I've tried all 3). What is wierd is I can scan a document on the same printer and see that on the same USB port. It is like I am missing some XP software or something to allow me to add a printer. My husband brought home a little HP printer photo printer he had at work and I can't see it either. HELP!
