Print complex script text through serial port from Windows Mobile system

I have a pocket PC with Windows mobile as OS. With it, I have a printer Zebra MZ320. My communication protocol is Bluetooth.

I connected the Bluetooth printer to the COM4 of the Windows mobile device.
I want now to print non ASCII code. The Windows mobile cannot support that, but at least it can print images.
So you have to convert your text and everything into image (the design depends on you) and print it.
First, take some files from Zebra website, the SDK and the ZebraUtilities, it's free after free registration.
If your printer is not Zebra, you can probably find a similar product from the vendor website.
Install the ZebraUtilities.cab on your Mobile device.
Use the DDLs from the SDK to your project by adding reference.
