Managing Print Orientations in Your React App

If you're developing a React application with various printable pages, it can be tricky to ensure that each page looks its best when printed. Some of your pages might require a landscape orientation for better visibility, while others are ideally suited to a portrait layout. So, how do you adapt the print settings to create the best possible printouts for each route? This guide explores a solution to help you manage print orientations effectively.

The Problem

In our case, we have a React app featuring approximately ten different routes, seven of which display optimally in landscape mode and the remaining three in portrait. The application is currently set up with a single print style defined in the App.scss file, which only supports portrait orientation by default. The challenge lies in seamlessly toggling between landscape and portrait orientations based on the current route.

To adapt the print orientation per route, we aim to dynamically set the @ page size using a functional approach within our React component.

The Solution

Step 1: Create a Function to Set Page Size

To manipulate the page size for printing, we can create a function that generates a <style> tag containing our desired @ page configuration. This function will allow us to switch between landscape and portrait orientations on-demand.

Step 2: Build the Print Component

Next, we will create a PrintIcon component that will handle the printing functionality. This component will incorporate the useEffect hook to call the setPageSize function:

Step 3: Dynamic Orientation Management

With the PrintIcon component in place, you can now manage the print orientation dynamically based on your application's routing. Simply pass the desired orientation ('landscape' or 'portrait') to the PrintIcon depending on the current route:

The useEffect hook will ensure that the correct @ page size is applied whenever the component mounts, and it will remove it when the component unmounts, keeping things tidy.

Additional Considerations

Browser Compatibility: Ensure that the solution is tested across different browsers, as print styles can vary in behavior.

Media Queries: For more complex scenarios, consider leveraging media queries to adjust print styles further depending on the page structure.

Conclusion

Having control over print orientation can significantly enhance the user experience when printing from your React application. With the steps outlined in this guide, you can implement a flexible solution that accommodates both landscape and portrait layouts for various routes.
