I just recently started to receive iPrint errors when accessing an iprint printer or print manager or driver store. I can open iManager and choose, for example, one of my IPP printers. As soon as I click OK I either get "page cannot be displayed" or this error
"Exception reading manager Information"
"java.net.SocketException: Unexpected end of file from server IPP Error: 0x1007"

I thought it might be a certificate issue but not sure. Anyone have an idea?
