I am using this plugin in ionic. This plugin does not initialise on device ready when running the app on iOS simulator. Below are the logs:

The problem seems to be only with Ionic, if I try with Cordova project it works perfect. Below are my ionic code:

    let content = 'hello world';
    let options = {
        name: 'MyDocument',
        //printerId: 'printer007',
        duplex: true,
        landscape: true,
        grayscale: true
     };
    this.printer.print(content, options).then(this.onSuccess, this.onError);

It always goes to error block on iOS platform and shows 'cordova_not_available' error. Works perfect on Android platform.

Please help me out to fix this issue. Thanks in advance.

I'm running into i think the same issue on Ionic4/5 + NodeJS : v13.12.0 + Xcode 11.4

TLDR; when i check

this.printer.isAvailable();

I'm getting:

[Error] ERROR – Error: Uncaught (in promise): TypeError: undefined is not an object (evaluating 'this.printer')

I have removed plugin/platform re-added same, updated modules rebuilt ad nauseam Does anyone know the cause? Have a fix? or even a workaround?

For Thoroughness :

Environment:

Ionic:

Ionic CLI : 5.4.16 (/Users/Shared/Opt/.npm/lib/node_modules/ionic) Ionic Framework : @ionic/angular 4.11.10 @angular-devkit/build-angular : 0.801.3 @angular-devkit/schematics : 8.1.3 @angular/cli : 8.1.3 @ionic/angular-toolkit : 2.0.0

Cordova:

Cordova CLI : 9.0.0 (cordova-lib@9.0.1) Cordova Platforms : browser 6.0.0, ios 5.1.1 Cordova Plugins : cordova-plugin-ionic-keyboard 2.2.0, cordova-plugin-ionic-webview 4.1.3, (and 10 other plugins)

Utility:

cordova-res : 0.11.0 native-run : not installed

System:

ios-sim : 8.0.2 NodeJS : v13.12.0 (/Users/Shared/Opt/bin/node) npm : 6.13.4 OS : macOS Catalina Xcode : Xcode 11.4 Build version 11E146

Project set up ran...

$ ionic capacitor add iOS $ ionic cordova prepare iOS

Plugin set up ran...

$ ionic cordova plugin add cordova-plugin-printer $ npm install @ionic-native/printer

Printer dir is present in Platforms:

In /package.json

"dependencies": { "@ionic-native/printer": "^5.23.0", "cordova-plugin-printer": "^0.8.0”, "cordova": { "plugins": { "cordova-plugin-whitelist": {}, }, "cordova-plugin-printer": {},

In: src/app/app.module.ts

import { Printer, PrintOptions } from '@ionic-native/printer/ngx’;

@NgModule({ providers: [ Printer,

In src/app/services/printer.service.ts

import { Printer, PrintOptions } from '@ionic-native/printer/ngx’;

constructor( private printer: Printer, private reporting: ScoreReportingService ) { }

In src/app/mod/results-print/results-print.page.ts

import { PrinterService } from '../../services/printer.service’;

constructor(
    private fb: FormBuilder,
    private printer: PrinterService
) { }

public printerWorks = this.printer.isAvailable();

ngOnInit() { cosole.log(printerWorks)

Getting the following error:
