我有一个Android应用程序，它与热敏打印机的英文打印效果很好.该代码是完美的.但是问题是当我传递阿拉伯字符或任何其他Unicode时，它无法正确打印.
I have Android app, which is working very well with English printing from the thermal printer. The code is perfect. But the problem is when I pass Arabic characters or any other Unicode it does not print properly.
问题出在代码页上.我在将字符串转换为字节时尝试了支持阿拉伯语和Unicode的其他代码页.它在阿拉伯语的日志中也显示了正确的字符串，但在打印时不起作用.
The problem is with a code page. I tried different codepage which supports Arabic as well as Unicode while converting strings to byte. It shows the proper string in the log also of Arabic, but when It prints it does not work.
注意:我的打印机支持阿拉伯语，代码页为32.我需要通用打印机解决方案.我没有使用Epson SDK.我正在使用ESC/POS命令.
Note: My printer supports Arabic and codepage is 32. I need a universal printer solution. I am not using Epson SDK. I am using ESC/POS commands.
推荐答案
最简单的方法是使用Epson SDK；因为它不在乎它是否是Epson打印机-只有USB设备的设备过滤器中的供应商ID在供应商之间有所不同；但是Star Micronics和其他100％兼容的设备都可以正常工作.如果您想编写自己的驱动程序，这实际上意味着重新发明轮子；请参阅 ESC/POS 附录C，第73页:
most easy would be to use the Epson SDK; because it does not care if it's an Epson printer - only the vendor ID in the device-filter for USB devices differs in between the vendors; but Star Micronics and other 100% compatibles work just fine. if you want to write your own driver, which literally means re-inventing the wheel; have a look at ESC/POS appendix C, page 73:
对于阿拉伯语，您需要使用ESC t命令选择字符表13，该命令是IBM代码页 CP864 .顺序为:\x1B \x74 \xD.输出也必须编码为CP864，并从UTF-16转换，以便与打印机期望的代码页匹配.
for Arabic you'd need to select character table 13 with the ESC t command, which is IBM code-page CP864. the sequence would be: \x1B \x74 \xD. the output also would have to be encoded as CP864, converted from UTF-16, so that it matches the code-page, which the printer then expects.
这篇关于Android热敏打印机阿拉伯文问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
