Hi

I have tested encoding with gb18030, cp936, cp949, ksc5601, cp950, big5.
It's not working,but working at cp866,cp863,cp860.
Please tell me how to fix it

Hello!

Does your printer have a Chinese font?
Please hold down the FEED button and turn on the printer.
The printer's information will be printed.

Thank you!
