ReactToPrint - Print React components in the browser

Build Status NPM Downloads dependencies Status npm version

So you've created a React component but would love to give end users the ability to print out the contents of that component. This package aims to solve that by popping up a new print window with CSS styles copied over as well.

Install

npm install --save react-to-print

Example

Calling from class components

import React from 'react';
import ReactToPrint from 'react-to-print';
 
class ComponentToPrint extends React.Component {
  render() {
    return (
      <table>
        <thead>
          <th>column 1</th>
          <th>column 2</th>
          <th>column 3</th>
        </thead>
        <tbody>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
        </tbody>
      </table>
    );
  }
}
 
class Example extends React.Component {
  render() {
    return (
      <div>
        <ReactToPrint
          trigger={() => <a href="#">Print this out!</a>}
          content={() => this.componentRef}
        />
        <ComponentToPrint ref={el => (this.componentRef = el)} />
      </div>
    );
  }
}

Calling from functional components with hooks

import React, { useRef } from 'react';
import ReactToPrint from 'react-to-print';
 
class ComponentToPrint extends React.Component {
  render() {
    return (
      <table>
        <thead>
          <th>column 1</th>
          <th>column 2</th>
          <th>column 3</th>
        </thead>
        <tbody>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
          <tr>
            <td>data 1</td>
            <td>data 2</td>
            <td>data 3</td>
          </tr>
        </tbody>
      </table>
    );
  }
}
 
const Example = () => {
  const componentRef = useRef();
  return (
    <div>
      <ReactToPrint
        trigger={() => <button>Print this out!</button>}
        content={() => componentRef.current}
      />
      <ComponentToPrint ref={componentRef} />
    </div>
  );
};

Running locally

NOTE: Node ^8.6 is required to build the library locally. We use Node ^10 for our CLI checks.

API

<ReactToPrint />

The component accepts the following props (note: ? denotes an optional prop):

Name Type Description
trigger function A function that returns a React Component or HTML element
content function A function that returns a component reference value. The content of this reference value is then used for print
copyStyles boolean? Copy all <style> and <link type="stylesheet" /> tags from <head> inside the parent window into the print window. (default: true)
onBeforeGetContent function? Callback function that triggers before the library gathers the page's content. Either returns void or a Promise. This can be used to change the content on the page before printing.
onBeforePrint function? Callback function that triggers before print. Either returns void or a Promise. Note: this function is run immediately prior to printing, but after the page's content has been gathered. To modify content before printing, use onBeforeGetContent instead.
onAfterPrint function? Callback function that triggers after print
onPrintError function(errorLocation: string, error: Error)? Callback function that will be called if there is a printing error serious enough that printing cannot continue. Currently limited to Promise rejections in onBeforeGetContent or onBeforePrint. Use this to attempt to print again. errorLocation will tell you in which callback the Promise was rejected.
removeAfterPrint boolean? Remove the print iframe after action. Defaults to false.
pageStyle string? Override default print window styling
bodyClass string? Class to pass to the print window body

FAQ

Why does react-to-print skip <link rel="stylesheet" href=""> tags?

<link>s with empty href attributes are INVALID HTML. In addition, they can cause all sorts of undesirable behavior. For example, many browsers - including modern ones, when presented with <link href=""> will attempt to load the current page. Some even attempt to load the current page's parent directory.

How do you make ComponentToPrint show only while printing?

If you've created a component that is intended only for printing and should not render in the parent component, wrap that component in a div with style set to { display: "none" }, like so:

<div style={{ display: "none" }}><ComponentToPrint ref={componentRef} /></div>

This will hide ComponentToPrint but keep it in the DOM so that it can be copied for printing.
