I have a Dell laptop running on Vista and a Packard Bell desktop running on XP. I am running a wireless network through a Belkin router. The desktop has a printer hardwired to it using a USB connection and I want to print from the laptop. I have Norton 360 running on both machines, the firewall of which is set to recognise both machines. I have set the printer properties to "sharing". On the laptop I can see the printer that I want to connect to, but I keep getting "access denied". On the desk-top I cannot see the lap-top at all. I have tried switching off the firewall. What am I doing wrong?
