Print in TypeScript DOCX Editor

14 Aug 202612 minutes to read

To print the document, use the print method from the TypeScript DOCX Editor (Document Editor) instance.

Refer to the following example for showing a document and printing it.

index.ts
index.html
import { DocumentEditor, Print } from '@syncfusion/ej2-documenteditor';
import { Button } from '@syncfusion/ej2-buttons';

DocumentEditor.Inject(Print);

let documenteditor: DocumentEditor = new DocumentEditor({
    enablePrint: true, height: '370px'
});
documenteditor.appendTo('#DocumentEditor');

let sfdt: string = `{
    "sections": [
        {
            "blocks": [
                {
                    "inlines": [
                        {
                            "characterFormat": {
                                "bold": true,
                                "italic": true
                            },
                            "text": "Hello World"
                        }
                    ]
                }
            ],
            "headersFooters": {
            }
        }
    ]
}`;

documenteditor.open(sfdt);
let printButton: Button = new Button();
printButton.appendTo('#print');
document.getElementById('print').addEventListener('click', () => {
    documenteditor.print();
});

index.ts
index.html

documenteditor.appendTo('#DocumentEditor');
let printButton: Button = new Button();
printButton.appendTo('#print');

document.getElementById('print').addEventListener('click', () => {
    documenteditor.print();

Improve print quality

The Document Editor provides an option to improve the print quality using printDevicePixelRatio in Document Editor settings. The Document Editor uses a canvas approach to render content. The canvas is then converted to an image and processed for print. Using the printDevicePixelRatio API, you can increase the image quality based on your requirement.

The following example code illustrates how to improve the print quality in the Document Editor container.

let container: DocumentEditorContainer = new DocumentEditorContainer({ enableToolbar: true, height: '590px',
   documentEditorSettings: {
     printDevicePixelRatio: 2
   }
 });
 DocumentEditorContainer.Inject(Toolbar);
 container.serviceUrl = 'https://document.syncfusion.com/web-services/docx-editor/api/documenteditor/';
 container.appendTo('#container');

NOTE

The Web API hosted link https://document.syncfusion.com/web-services/docx-editor/api/documenteditor/ utilized in the Document Editor’s serviceUrl property is intended solely for demonstration and evaluation purposes. For production deployment, please host your own web service with your required server configurations. You can refer and reuse the GitHub Web Service example or Docker image for hosting your own web service and use for the serviceUrl property.

NOTE

By default, the printDevicePixelRatio value is 1.

Print using window object

You can print the document in the Document Editor by passing the window instance. This is useful to implement print in third-party frameworks such as Electron, where the window instance will be available. Refer to the following example.

import { DocumentEditor, Print } from '@syncfusion/ej2-documenteditor';

DocumentEditor.Inject(Print);

let documenteditor: DocumentEditor = new DocumentEditor({
    enablePrint: true, height: '370px'
});
documenteditor.appendTo('#DocumentEditor');
documenteditor.print(window);

Page setup

Some of the print options cannot be configured using JavaScript. Refer to the following links to learn more about the browser page setup:

However, you can customize margins, paper, and layout options by modifying the section format properties using the page setup dialog.

import { DocumentEditor, Print, PageSetupDialog, Editor, Selection, EditorHistory } from '@syncfusion/ej2-documenteditor';

DocumentEditor.Inject(Print, PageSetupDialog, Editor, Selection, EditorHistory);

let documenteditor: DocumentEditor = new DocumentEditor({
    isReadOnly: false,
    enablePrint: true,
    enablePageSetupDialog: true,
    enableEditor: true,
    enableSelection: true,
    enableEditorHistory: true,
    height: '370px'
});
documenteditor.appendTo('#DocumentEditor');
documenteditor.showPageSetupDialog();

By customizing margins, papers, and layouts, the layout of the document will be changed in the Document Editor. To modify these options during the print operation, serialize the document as SFDT using the serialize method in the Document Editor instance and open the SFDT data in another instance of the Document Editor in a separate window.

The following example shows how to customize layout options only for printing.

index.ts
index.html
import { DocumentEditor, Print, Editor, Selection, EditorHistory, SfdtExport } from '@syncfusion/ej2-documenteditor';
import { Button } from '@syncfusion/ej2-buttons';

//Inject require modules.
DocumentEditor.Inject(Print, Editor, Selection, EditorHistory, SfdtExport);

let documenteditor1: DocumentEditor = new DocumentEditor({
    isReadOnly: false,
    enablePrint: true,
    enableEditor: true,
    enableSelection: true,
    enableEditorHistory: true,
    enableSfdtExport: true,
    height: '370px'
});
documenteditor1.appendTo('#DocumentEditor');
let printButton: Button = new Button();
printButton.appendTo('#print');

let documenteditor2: DocumentEditor = new DocumentEditor({
    enablePrint: true, enableSelection: true, isReadOnly: false, enableEditor: true, height: '370px'
});
documenteditor2.appendTo('#DocumentEditor2');
//Print the document
document.getElementById('print').addEventListener('click', () => {
    let sfdtData = documenteditor1.serialize();
    documenteditor2.open(sfdtData);
    //Set A5 paper size
    documenteditor2.selection.sectionFormat.pageWidth = 419.55;
    documenteditor2.selection.sectionFormat.pageHeight = 595.30;
    documenteditor2.print();
});
