Angular 14 ngx-print Project to Print HTML to PDF Document With Custom CSS Classes in TypeScript

Welcome folks today in this blog post we will be printing certain sections of html document to pdf document with custom css classes using ngx-print library in Typescript. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new angular project using the below command as shown below

ng new sampleapp

npm i ngx-print

And after that you need to see the below directory structure of the angular project as shown below

And then we need to go to app.module.ts file and copy paste the following code

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
 
import { AppComponent } from './app.component';
 
import { NgxPrintElementModule } from 'ngx-print-element';
 
@NgModule({
  imports: [
    BrowserModule,
    NgxPrintElementModule,
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

import { NgModule } from '@angular/core';

import { BrowserModule } from '@angular/platform-browser';

import { AppComponent } from './app.component';

import { NgxPrintElementModule } from 'ngx-print-element';

@NgModule({

imports: [

BrowserModule,

NgxPrintElementModule,

declarations: [AppComponent],

bootstrap: [AppComponent],

})

export class AppModule {}

As you can see we are importing the ngx-print-element module and then we are including it inside the imports array.

And then you need to go to app.component.html file and copy paste the following html code

app.component.html

<div class="container">
  <h2 class="my-3">ngx-print-element</h2>
 
  <table id="demo" class="table table-bordered">
    <tr>
      <th>No</th>
      <th>Company</th>
      <th>Contact</th>
      <th>Country</th>
    </tr>
    <tr class="print-none" style="background: greenyellow"><!-- No print -->
      <td>01</td>
      <td>Alfreds Futterkiste</td>
      <td>Maria Anders</td>
      <td>Germany</td>
    </tr>
    <tr>
      <td>02</td>
      <td>Centro comercial Moctezuma</td>
      <td>Francisco Chang</td>
      <td>Mexico</td>
    </tr>
    <tr>
      <td>03</td>
      <td>AIS Playground</td>
      <td>Nakhon Pathom</td>
      <td>Thailand</td>
    </tr>
    <tr class="print-none" style="background: greenyellow"> <!-- No print -->
      <td>04</td>
      <td>FPT Software</td>
      <td>Cau Giay</td>
      <td>Vietnamese</td>
    </tr>
  </table>

As you can see we have different html sections out there we have paragraphs and table and then we have the popup window where we allow the user to print various sections of the html to pdf document.

Now you need to go to app.component.ts file and copy paste the following code

app.component.ts

import { Component } from '@angular/core';
import { NgxPrintElementService } from 'ngx-print-element';
 
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
})
export class AppComponent {
  constructor(public print: NgxPrintElementService) {}
 
  public config = {
    printMode: 'template-popup',
    popupProperties: 'toolbar=yes,scrollbars=yes,resizable=yes,top=0,left=0,fullscreen=yes',
    pageTitle: 'Hello World',
    // templateString: '<header>I\'m part of the template header</header>{{printBody}}<footer>I\'m part of the template footer</footer>',
    stylesheets: [{ rel: 'stylesheet', href: 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css' }],
    styles: ['.table { color: red; }', '.table td { color: green; }']
  };
}

import { Component } from '@angular/core';

import { NgxPrintElementService } from 'ngx-print-element';

@Component({

selector: 'my-app',

templateUrl: './app.component.html',

styleUrls: ['./app.component.scss'],

})

export class AppComponent {

constructor(public print: NgxPrintElementService) {}

public config = {

printMode: 'template-popup',

popupProperties: 'toolbar=yes,scrollbars=yes,resizable=yes,top=0,left=0,fullscreen=yes',

pageTitle: 'Hello World',

// templateString: '<header>I\'m part of the template header</header>{{printBody}}<footer>I\'m part of the template footer</footer>',

stylesheets: [{ rel: 'stylesheet', href: 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css' }],

styles: ['.table { color: red; }', '.table td { color: green; }']

};

}
