Text justification question

This is the first time I have been using Zebra printer (KR-403). I would like to print longer text which will be justified. It is possible to use ^FB command and J parameter for that. But the problem I am facing right now is that I need to use Unicode for my text. The thing is ^FB does not support TrueType fonts, and for that you need to use ^TB command. ^TB only manage to print text in some box, but still that text is not justified.

My question is: Is there any other way I can make my text justified, along side using Unicode.

Thanks in advance
