I am not sure... I saw Chinese text directly printed out when power-on
the printer with 'font' button pressed (means to print a setting menu).
Besides, the printer said it has a Chinese font stored in the printer,
however I cannot manage to print them out. E.g. 'echo 中文 > /dev/lp0'
only produce junk. Both UTF-8 and GB18030 has been tried.

Ah, yes, and now I purchased a second new wire, the result is.... the
same! This is really frustrating because this is the final last
show-stopper for us to move this shop to move everything to Linux. 

Is it possible that this has something to do with the special printer
model? Because it is LQ-300K model, K probably means it has Chinese font
in it, there might be tiny difference between the real LQ-300 model.
