Solution 1:

Greeting,

Your program is great and works fine.

The problem is the character encoding passed to the printer. Somewhere in the network from your program to the printer, the UTF-8 encoding (java default) is converted to other encoding.

Check the printer default encoding, it might be possible to change. If cannot change default printer encoding, change the java encoding accordingly.

Also if you have a proxy/filter/firewall in the network it might change encoding as well.

Update

Change default printer encoding with operating system printer's default settings.

Change Java encoding answered here.
