PHP 到 Zebra 打印机

Question

我将这台 Zebra ZM400 打印机连接到网络 (192.168.1.50)。我正在尝试直接从 PHP 将内容推送到这台打印机。

这就是我的想法，但我无法做到这一点。我尝试了 file_put_contents('192.168.1.50', $content) 但没有成功。

如果有人能帮我解决这个问题，我将不胜感激。谢谢:-)

解决方案:

我使用 LPR 协议(protocol)打印。无需安装驱动程序或任何东西。 PHP 5 的 LPR 打印类可以从这里下载:

Answer 1

我有一个类似的问题，当时我使用 java 程序在没有打印驱动程序的情况下打印到 zebra 打印机，并想使用 PHP 重新创建它。找不到答案让我很烦恼。通过一些用Wireshark抓包对比两者，感觉是可以的。我终于偶然发现了解决方案(至少对我而言)。这将直接从 PHP 页面将标签打印到联网的 Zebra 打印机，无需驱动程序。
