I have a Kodak ESP 7 wireless printer. I bought the printer specifically for the wireless capability. The network I have is secured and so I had to connect the printer with a password. Now every time I try and use the printer my computer says it cannot detect it. The printer says that it is connected to the correct network and if I reconnect it will work. After a while, once the printer goes into what looks like a sleep mode, then when I try to print it will not until I reconnect. I am using the Windows 7. Does anyone know how to fix this problem?
