If the computer cannot discover the printer, then the printer software cannot be installed on the computer. · Lost connection: If the printer is connected to a wired or wireless network that uses DHCP or AutoIP to assign IP addresses, then if the printer IP address changes, a software firewall can prevent the computer from finding the printer on the network even if the printer software has been successfully installed on the computer. Solution In order for the printer to be usable on a network on which computers are protected by a software firewall, you must do the following: 1. 2.
