#Introduction

If you need to use a driver that isn't supported by the package, you can easily add your own custom driver. Adding a custom driver will require you to add the driver's config to the drivers in the config file, and to extend the printing factory in a service provider.

#Configuring a Custom Driver

Add your custom driver configuration under drivers in config/printing. The minimum required for your driver config is a driver key.

'driver' => 'my_custom_driver',

'drivers' => [
    ...
    'my_custom_driver' => [
        'driver' => 'custom', // This value is required
        // any other configuration needed
    ],
],

You can change custom and my_custom_driver to whatever you want. Any data you specify in the configuration of your custom driver will be passed to the closure you provide to the printing factory when extending it.

#Defining a Custom Driver

Once you have your custom driver configuration defined, you need to tell the printing package how to create it. This is done by extending the print factory used by this package. In a service provider, you can do it like this:

public function register(): void
{
    $this->app['printing.factory']->extend('custom', function (array $config) {
        return new MyCustomDriver($config);    
    });
}

The value you pass in as the first parameter needs to match what you defined as driver in your custom driver's configuration earlier.
