Greetings, Both legacy boxes run FC3. According to /etc/cups/printers.conf, device URI on Server is usb:/dev/usb/lp0 device URI on Client is ipp://192.168.0.2:631/printers/deskjet-5550-2 Server is set to share to 192.168.0.0/255.255.255.0 Both machines ping each other. Both machines have port 631 udp & tcp open. Why can't client print to server? I get "Network host 192.168.0.2 is busy; will retry in 30 seconds". Thank you, Steve
