I have a new Dell Studio Windows 7 computer with a locally connected printer that works with this machine. I have a wireless router that is the access to the internet for two XP laptops and two iPhones. All access the internet without difficulty. I have been able to share files from the Windows 7 machine with the laptops. I can find the printer on the network with the laptops. When I try to print nothing happens. In My Network Places the printer is listed on the laptop with the footer Access denied. My windows 7 machine came with McAfee installed that controls the Windows firewall but I turned off the firewall in McAfee without effect. Any ideas?
