中文字符热敏打印 字符大小调整

请教一下大家如何使用Devterm内置的热敏打印机打印中文字符以及如何调整字符大小,我现在手持的是Devterm-a06,感谢

supported already
but need to comment out

from line 129 to 133

then re-compile the thermal printer code , restart devterm_thermal_printer.elf

then you can print unicode characters
like

echo "日月火水木金土 ΕΙΝΑΙ Ο ΘΕΟΣ ΓΕΩΜΕΤΡΗΣ" > /tmp/DEVTERM_PRINTER_IN
