Arabic Text using iMZ320 from Windows Phone 8 App.

Hi,

I try to print Arabic Text using iMZ320 mobile printer from windows phone 8 (Silver light) Application. But I am unable to print Arabic Text. It prints the unreadable characters like "ميد". I try to install the Swiss 721 bt Arabic font but I didn't get the Swiss 721 font file to download and install.
Please help to me.

 

Thanks.
