I have recently purchased the above printer and everything works great - wireless printer reprint etc etc but my 4s keeps displaying no air printers found when I try and print to it. I have a Huawei echolife hg532 firmware v2.02t router. Someone has told me that this router firmware does not support AirPrint! Does anyone know if this is true or has any ideas how I could solve this as it is causing me major issues - many thanks
