I just bought a new wireless HP Photosmart C4580 All-in-One printer, scanner, copier. I want to know if I can use it with both of my two wireless laptops. My new HP wireless laptop is connected to the Internet with an Alltel wireless card and my older Gateway wireless laptop connects to the Internet through dial-up. I have no DSL high speed Internet, so I am wondering if just installing the new printer software on both laptops would allow me to print from both laptops to the new wireless printer. Do I need to buy anything extra to make this work, like a router? Or do I have to set up a network between both laptops and the printer? If so, I have no idea how to do that. Can anyone help me? thanks.
