Ionic 3 -> TypeError: Printer_1.getPlugin(...).check 不是函数

如何解决Ionic 3 -> TypeError: Printer_1.getPlugin(...).check 不是函数

我检查了论坛是否存在此问题，我发现了这篇帖子 (https://forum.ionicframework.com/t/native-printer-plugin-not-working/92148) 这正是我遇到的情况，但我无法修复它：皱眉：

这是一个 Ionic 3 项目。

如果有人可以帮助我，我会把我能提供的所有信息都放在这里。我可以说这是一个遗留项目（我不知道编程中的遗留是否有我想解释的同一个术语。A 人开始项目，而我作为 B 人继续项目。）

Ionic:

   Ionic CLI          : 6.16.3 (/Users/samy/.nvm/versions/node/v11.9.0/lib/node_modules/@ionic/cli)
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.3

Cordova:

   Cordova CLI       : 10.0.0
   Cordova Platforms : 9.1
   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.2.0,cordova-plugin-ionic-webview 2.5.2,(and 19 other plugins)

Utility:

   cordova-res (update available: 0.15.3) : 0.6.0
   native-run (update available: 1.4.0)   : 1.3.0

System:

   Android SDK Tools : 26.1.1 (/Users/samy/Library/Android/sdk)
   NodeJS            : v11.9.0 (/Users/samy/.nvm/versions/node/v11.9.0/bin/node)
   npm               : 7.9.0
   OS                : macOS Big Sur

package.json 如下：

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......拜托......我祈求你的帮助。

非常感谢，山姆
