我希望添加使用 Dymo LabelWriter 450 Turbo 打印多个标签的功能。我已经从 Dymo 网站下载了 DYMO-Label-v.8-SDK.dmg，但看不到任何 Javascript/Web 相关的 SDK 文件或文档 - 我只能看到 AppleScript 示例，这在这里没有帮助。
有谁知道这是否可能（标签数据将来自连接到 PHP Web 应用程序的后端数据库）。我在 Dymo Developer 网站上找不到 Javascript SDK 的任何文档 - 只有几年前的一些示例，所以甚至不确定当前状态是什么、最新版本是什么等等，以及是否有办法打印多个标签？
实际上，我刚刚使用完全相同的打印机在我自己的网络应用程序中构建了此功能，今天我感觉很友好。这是我在生产级应用程序中为我工作的内容。祝你好运！
