android - Ionic 3 -> TypeError: Printer_1.getPlugin(...).check 不是函数
问题描述
我检查了这个问题的论坛，我发现了这篇文章（https://forum.ionicframework.com/t/native-printer-plugin-not-working/92148）这正是发生在我身上但我无法解决它：皱眉：
这是一个 Ionic 3 项目。
如果有人可以请帮助我，我会在这里提供我可以提供的所有信息。我可以说这是一个遗留项目（我不知道编程中的遗留是否与我想解释的术语相同。A 人开始项目，而我作为 B 人继续项目。）

当我执行 this.printer.isAvailable() 时，错误如下：

我有点绝望，因为这是为了我的公司，所以......请......我祈祷你的帮助。
