Question: Unable to print Simplified Chinese & Japanese characters (Epson TM-T82X)

[Zames Chua]

Hi receiptline team! I'm really loving what you guys are building so far.

I'm trying to print Simplified Chinese characters onto using escpos command on an Epson TM-T82X printer, but I'm getting gibberish instead.
For context, I'm using this in a React-Native app.
Also, it seems like Chinese printing is supported from the official docs for this specific printer model.

Chinese

receiptline document

Printer config

const printer = {
  encoding: 'gb18030', // and cp936
  command: 'escpos',
};

Japanese

I tried printing the Japanese sample afterwards to test it and there was a similar problem

const printer = {

  command: 'escpos',

Here's the working English sample for comparison.

Thank you team in advance!

Just an update from the printer supplier, the printer is able to support Chinese printing mode but there's a setting to enable multi-language font.

Just checking to see if you know a way to configure the setting via ESCPOS commands

Thank you for using receiptline!

We don't have this model, so I tried to find a similar model.

敏捷的棕色狐狸跳过懒狗 printed correctly with the following steps

• Change the multi-language font setting to Simplified Chinese with the utility.
• Set encoding to gb18030 in the receiptline options.

I expected the command to set the multi-language font is GS ( E, but it was not listed in the ESC/POS command reference.

I think the manufacturer would like you to set it up with the utility.

Hi @receiptline,
Thank you so much for taking a jab at the question! I'll be trying that out and let you know how it goes :)

Just wanted to give an update, everything works after I configured the printer with the Epson utility.
I still hope to know if there's ever a way to configure it from ESC/POS commands if anyone ever finds out.

Thank you again!

Following up on this, can you share how you got this package to work with React Native? I am trying to do the same thing. Thank you.

Hello!

I found an article by a user who tried to run receiptline with React Native. Sorry for the Japanese article.
