What are the potential pitfalls of attempting to use PHP to determine the paper size of a client's printer for image printing?

One potential pitfall of attempting to use PHP to determine the paper size of a client's printer for image printing is that PHP does not have direct access to client-side printer settings. A workaround could be to prompt the user to select the paper size before printing the image. 

<?php
// Prompt the user to select the paper size
echo '<select name="paper_size">';
echo '<option value="A4">A4</option>';
echo '<option value="Letter">Letter</option>';
echo '</select>';
?>
