trying to print with Hebrew Fonts

Hey,

Trying to print Hebrew and I get Gibberish.

 

Noticed that Printer has SWISS 721 Font

Noticed that when Printer ( QLN220) is connected to PC using Zebra Design it works.

 

my ISVs have a written application and need to understand what needs to be done in order to print Hebrew...

 

I have given them our SDK.

 

Can you please help me understand what they are missing?

 

Best'
