I have my printer connected and shared to computer #1 via usb. When I try to set up to use that printer on another computer, I find it on my network it connects, installs the necessary drivers and it "seems" to be connected. But, when I try to print from computer #2 I get an error box stating that there is no printer installed and to install one via Printers and Faxes. Then, when I check to see if the printer is indeed installed it says that it is disconnected. Do you think it might be the firewall settings on computer #1? I appreciate the help.
