The PDF Viewer supports printing the loaded PDF file. You can enable/disable the print using the following code snippet.

import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [documentPath]='document'
                            [enablePrint]='true'
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
  }
import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [serviceUrl]='service'
                            [documentPath]='document'
                            [enablePrint]='true'
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public service = 'https://services.syncfusion.com/angular/production/api/pdfviewer';
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
  }

You can invoke print action using the following code snippet.,

<script>
    window.onload = function () {
        var pdfViewer = document.getElementById('pdfviewer').ej2_instances[0];
        pdfViewer.print.print();
    }
</script>

PDF Viewer extension supports printing functionality for loaded PDF files directly within the browser. You can utilize the printMode parameter to specify the printing mode, with the option to choose NewWindow for printing. Below is a code snippet demonstrating how to implement this functionality

import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [documentPath]='document'
                            [printMode] = "printMode"
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public document: string = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    public resource: string = "https://cdn.syncfusion.com/ej2/23.1.43/dist/ej2-pdfviewer-lib";
    public printMode: string = "NewWindow";
  }
import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [serviceUrl]='service'
                            [documentPath]='document'
                            [printMode] = "printMode"
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public service = 'https://services.syncfusion.com/angular/production/api/pdfviewer';
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    public printMode: string = "NewWindow";
  }

By setting the printMode to NewWindow, the extension will open a new window for printing the PDF document, providing a seamless and user-friendly printing experience.

Limiting the Dialog Opening for Printing

In the Syncfusion® PDF Viewer, you can control the printing process by leveraging the printStart event. This event enables you to customize the printing behavior, particularly restricting the dialog opening. Below is a code snippet demonstrating how to utilize this event

import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, PrintStartEventArgs, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [documentPath]='document'
                            (printStart)="printStart($event)"
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public document: string = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    public resource: string = "https://cdn.syncfusion.com/ej2/23.1.43/dist/ej2-pdfviewer-lib";
    ngOnInit(): void {
    }
    printStart(args: PrintStartEventArgs){
      console.log(args);
      args.cancel = true; 
    }
}
import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, PrintStartEventArgs, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [serviceUrl]='service'
                            [documentPath]='document'
                            (printStart)="printStart($event)"
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public service = 'https://services.syncfusion.com/angular/production/api/pdfviewer';
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';

    ngOnInit(): void {
    }
    printStart(args: PrintStartEventArgs){
      console.log(args);
      args.cancel = true; 
    }
}

In this code snippet, the printStart function is defined to handle the printStart event. By setting args.cancel to true, the print dialog opening is restricted. By default, the cancel property is set to false.

Customizing Print Quality using printScaleFactor API

The PDF Viewer allows you to adjust the print quality using the printScaleFactor API. The quality of the print improves as the print quality value increases from 0.5 to 5.

When the value is less than 0.5, the PDF is printed at a standard quality. When the value exceeds 5, the PDF is still printed at the standard quality. In standard quality, printScaleFactor value is set to 1 as default value.
The effective range for print quality is between 0.5 and 5. Higher values within this range will result in better print quality, but also increase the print time.

By default, the printScaleFactor is set to 1.

import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [documentPath]='document'
                            [enablePrint]='true'
                            [printScaleFactor]='printScaleFactor'
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    //pdf with low quality. By changing values you can change the quality of the pdf.
    public printScaleFactor = 0.5;
  }
import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         TextSearchService, AnnotationService, TextSelectionService,
         PrintService
       } from '@syncfusion/ej2-angular-pdfviewer';
@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                  <ejs-pdfviewer id="pdfViewer"
                            [serviceUrl]='service'
                            [documentPath]='document'
                            [printScaleFactor]='printScaleFactor'
                            [enablePrint]='true'
                            style="height:640px;display:block">
                  </ejs-pdfviewer>
              </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
  })
  export class AppComponent implements OnInit {
    public service = 'https://services.syncfusion.com/angular/production/api/pdfviewer';
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    //pdf with low quality. By changing values you can change the quality of the pdf.
  public printScaleFactor = 0.5;
  }
