PosBox模块通过树莓派的硬件盒子打印出来的中文出现乱码

vFire

最近一直在捣鼓树莓派的posbox，非常不错，唯一的问题就是。。。打印出来的中文乱码啊，同志们有研究过这个的没有，求指点~~~
不是本地打印的那个哦，本地没问题，但是通过树莓派打印就不行，中文出现一堆的“北北北”这样的乱码字符，查看官方文档说ESCOP打印指令暂时还不支持中文，崩溃啊~~~

在escpos模块下的constants.py文件中第93行（附近）添加下面一行

TXT_ENC_PC936 =&#039;\x1C\x21\x00&#039;

然后在escpos.py文件的第813行附近添加下面一行：

 &#039;cp936&#039;: TXT_ENC_PC936

最后，在escpos.py文件中的第838行注释掉原来一行附近添加一行：

#encoding = &#039;cp437&#039;<br />&nbsp; &nbsp; &nbsp; &nbsp;  encoding = &#039;cp936&#039;

即，在constants.py文件中添加对中文的编码支持，蓝后在escpos.py文件中引用新添加的encoding,最后的encode_char看起来大概是这个样子的:

def encode_char(char):&nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &quot;&quot;&quot; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Encodes a single utf-8 character into a sequence of <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; esc-pos code page change instructions and character declarations <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &quot;&quot;&quot; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; char_utf8 = char.encode(&#039;utf-8&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; encoded&nbsp; = &#039;&#039;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; encoding = self.encoding # we reuse the last encoding to prevent code page switches at every character<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; encodings = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # TODO use ordering to prevent useless switches<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # TODO Support other encodings not natively supported by python ( Thai, Khazakh, Kanjis )<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp936&#039;: TXT_ENC_PC936,&lt;-----新加的<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp437&#039;: TXT_ENC_PC437,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp850&#039;: TXT_ENC_PC850,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp852&#039;: TXT_ENC_PC852,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp857&#039;: TXT_ENC_PC857,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp858&#039;: TXT_ENC_PC858,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp860&#039;: TXT_ENC_PC860,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp863&#039;: TXT_ENC_PC863,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp865&#039;: TXT_ENC_PC865,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp866&#039;: TXT_ENC_PC866,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp862&#039;: TXT_ENC_PC862,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp720&#039;: TXT_ENC_PC720,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;iso8859_2&#039;: TXT_ENC_8859_2,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;iso8859_7&#039;: TXT_ENC_8859_7,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;iso8859_9&#039;: TXT_ENC_8859_9,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp1254&#039;&nbsp;  : TXT_ENC_WPC1254,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp1255&#039;&nbsp;  : TXT_ENC_WPC1255,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp1256&#039;&nbsp;  : TXT_ENC_WPC1256,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp1257&#039;&nbsp;  : TXT_ENC_WPC1257,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;cp1258&#039;&nbsp;  : TXT_ENC_WPC1258,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;katakana&#039; : TXT_ENC_KATAKANA,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; remaining = copy.copy(encodings)<br /><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if not encoding :<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; #encoding = &#039;cp437&#039; &lt;----注释掉<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; encoding = &#039;cp936&#039;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  ……<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

然后再重启服务，你就会发现中文好使了。
Good luck!

赞, 就是给 escpos 添加 cp936 编码的支持吧?

看整理一下提到官网github 好了...
谢谢贡献...

已提交给 py-xml-escpos 不知道官网什么时候能合并

KevinKong

直接提给Odoo官方不行么，我看他们都改了escpos的文件

太谢谢了~ 一下子就搞定了，之前联络了odoo的官方支持，他们也还没搞定或者说顾得上搞定，搜遍全网都没找到这个解决方法，兄弟，在上海不，我要请你吃饭。。。！！！版主，你可以来蹭一下~：）

OK , 官网 v8.0 分支已经合并进去了...
到时看看 master v9.0 分支是否合并...

;)Cool

不过看着你们沟通的过程，感觉朝官网提交个代码好费劲啊~~

請問我們打印機(EPSON TM-T88IV)只有支援BIG5編碼

我們印出來的中文字都會顯示控控控控

請問該如何修改呢？
