Java Printing

I have this piece of code for thermal printing ( I attached file) inside a large project, I need to print UTF-8 letters, but I can't, when I use 'DocFlavor flavor = [login to view URL]' with

'bytes = [login to view URL](StandardCharsets.UTF_8);'

the non-english (Arabic) letters change to a random symbols.

and when

I use 'DocFlavor.BYTE_ARRAY.TEXT_PLAIN_UTF_8' or

'DocFlavor.BYTE_ARRAY.TEXT_PLAIN_UTF_8'

java return

null exception

'[login to view URL]: Cannot invoke "[login to view URL]()" because "service" is null'
