Hi, from few days i can’t see my printer on PreForm! My printer is connected on WiFi normally (i can see its IP from my router)… I tryed to connect it by Ethernet… I added a rule in Windows Firewall for PreForm… I turned off Windows Firewall… I turned off the AntiVirus… Re-installed PreForm… I can’t add manually my Printer by IP… What going on? ---
