What are some best practices for integrating GD images with printer functions in PHP?

When integrating GD images with printer functions in PHP, it is important to ensure that the image is properly formatted for printing and that the printer settings are correctly configured. One common issue is that the image may not be in the correct resolution or color mode for printing. To solve this, you can use the `imagesetresolution()` function in GD to set the image resolution for printing. 

// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Set the resolution for printing
imagesetresolution($image, 300, 300);

// Send the image to the printer
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);
