Printing 打印机错误（EX_超时）Epson TM-T88V-I与Epson.ePOSBuilder 爱普生TM-T88V-i型。 连接到局域网。 Ping响应正常。 打印状态表OK。

我可以访问打印机配置页面

在配置页面-部分设备在打印机本地打印机的测试打印按钮中引发错误，错误：EX_TIMEOUT出现超时

参考ePOS打印API/XML：

简单测试网站：

print.html

<script type="text/javascript" src="js/epos-print-3.0.0.js"></script>

请求服务.cgi：

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <epos-print xmlns="http://www.epson-pos.com/schemas/2011/03/epos-print">
            <text>Test Print!!&#10;</text>
            <feed line="1"/>
            <cut/>
        </epos-print>
    </s:Body>
</s:Envelope>

要求正确

Sucess="False" code="DeviceNotFound" status="0"

Windows应用程序示例显示了相同的响应：

两种可能性：

打印机的设备id与本地打印机不同-请检查配置页面

或者ePOSPrint函数不允许直接发送url。我现在正在为同一台打印机构建一个应用程序，在我的第一个测试页面上显示的内容与您的不同：

var epos = new epson.ePOSPrint();
epos.address = 'http://192.168.0.1/cgi-bin/epos/services.cgi?devid=local_printer&timeout=6000';

请注意空url以及初始化后url的传递方式

---

检查后，看起来我的其他测试代码确实将url作为参数提交给了函数，就像您提交的一样，所以我唯一的猜测是设备id local_printer不正确。

但是我们如何获得设备id，因为在配置页面中没有类似设备id的内容？我再也无法访问打印机了，但我相信local_printer可能是打印机的原始名称=设备ID，所以我从它开始。semmelbroesel。我在上面发现了一些东西一些打印机配置页面是不同的。我有TM82-i，它比TM-U220-B和TM-88V-i有很多选择。在配置页面中，我可以设置TM-82-i的设备id。
