Chinese cp936 support

Bug description

Actually this is not a bug, but a question. I am looking to use this lib to print Chinese characters (cp936), has no luck to succeed yet. The platform is beaglebone.

Any help is appreciated.

Steps to reproduce

– I am adding a new printer in the profile:

  RD-DH32:
  name: RD-DH32
  vendor: Rongda Beijing
  inherits: default
  notes: >
      RD-DH32 http://www.rd-cn.com/uploadfile/2015/1029/20151029014450556.pdf.
  features:
    barcodeB: false
    bitImageColumn: true
    bitImageRaster: true
    graphics: false
    qrCode: false
    pdf417Code: false
    starCommands: True
  codePages:
    0: CP936

– And provide the magic_encode_args in the printer arguments, such as:

code:: python

magic_encode_args = dict(encoding='cp936')
p = Dummy(profile='RD-DH32', magic_encode_args=magic_encode_args)
p.text(u"荣")  # 打印文字
out = p.output
for i in out:
    print "0x{0:02x}".format(ord(i))

Looks like I got things incorrect: 0x3f

I am considering the method is incorrect. Any hints will be appreciated.

Device info

#coding=utf8

from escpos.printer import Serial
""" Seiko Epson Corp. Receipt Printer M129 Definitions (EPSON TM-T88IV) """
Epson = Serial('COM6')
Epson.codepage="gb2312"   #设置解码的类型
# Print text

Epson.text(u"你好\n"
           u"   测试你好\n"
           u"   空格\n"
           u"              飞\n"
           u"")

@2q1w2007 只需要设置一下codepage就可以了。

@NullYing Hi, thanks for the solution, it’s a stable solution. I’ve use it in my program.

I can print with chinese characters in master branch, but I can’t find a better way

p = Dummy()
p._raw("中文\n".encode('GB18030'))
p.cut()

I installed a new version of escpos today:

print(escpos.__version__)
3.0a8

According to you try and some source code reading, I found I could print Chinese characters correctly by just this line:

printer._raw("中文\n".encode('GB18030'))

Even don’t need to set the codepage.
