Directive Usage

The NgxPrintify directive allows you to trigger print functionality directly from your templates.

Step 1: Import the Module

Make sure to import the NgxPrintifyModule in your Angular module.

import { NgxPrintifyModule } from 'ngx-printify';

@NgModule({
  imports: [
    NgxPrintifyModule,
    // other imports
  ],
})
export class AppModule {}

Step 2: Using the Directive in Templates

You can use the ngxPrintify directive in your component templates as follows:

<div id="printArea1">
  <h1>Content of Print Area 1</h1>
  <p>This is the content that will be printed from printArea1.</p>
</div>

<div id="printArea2">
  <h1>Content of Print Area 2</h1>
  <p>This is the content that will be printed from printArea2.</p>
</div>

<ng-template #printTemplate>
  <h1>Print This Title</h1>
  <p>This is the content to print.</p>
  <div class="highlight">Highlighted content.</div>
</ng-template>

<button ngxPrintify 
        [printItemsId]="'printArea1,printArea2'"  <!-- Allow multiple IDs separated by commas -->
        [printTemplate]="printTemplate" 
        [printTitle]="'Print Example'" 
        [useExistingCss]="true" 
        [printStyle]="{ h1: { color: 'red' }, '.highlight': { border: 'solid 1px' } }" 
        [closeWindow]="true" 
        [previewOnly]="false">
  Print
</button>

Service Usage

The NgxPrintifyService can be used for more programmatic control over printing.

Step 1: Import the Service

Inject the NgxPrintifyService into your component:

import { Component, TemplateRef, ViewChild } from '@angular/core';
import { NgxPrintifyService } from 'ngx-printify';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
})
export class ExampleComponent {
  @ViewChild('printTemplate') printTemplate!: TemplateRef<any>;

  constructor(private printService: NgxPrintifyService) {}

  print() {
    this.printService.print({
      printItemsId: 'printArea1,printArea2', // Allow multiple IDs separated by commas
      printTemplate: this.printTemplate, // Pass the TemplateRef here
      printTitle: 'Print Example',
      useExistingCss: true,
      printStyle: {
        h1: { color: 'red' },
        '.highlight': { border: 'solid 1px', color: 'blue' }
      },
      closeWindow: true,
      previewOnly: false,
      printWindowOptions: {
        width: 800,
        height: 600
      }
    });
  }
}
