1 Thai Character printout wrongly but preview report good

HI Experts,

I have a problem when printing Thai Characters in report.

When preview the thai characters displayed perfectly.

But when printout - Only 1 character is printed wrongly.

Example: สำ

it will be printed as ส0

I've used other printer to test and same results appeared.

I've also print other printing but it prints correctly.

Not too sure if its the printer problem now or the report.

Some of the Thai words are maintained in the translation and some retrieve from table. But it prints out incorrectly.

Any ideas?

Thank You in advance
