Customizing bookings-event-printable.php

Hello fellow hackers. I’m using Events Manager Pro and want to add data to the Printable Bookings page (events-manager/templates/templates/bookings-event-printable.php) that corresponds to the custom fields I created in the Forms Editor. Those fields are:

parent
other_names
special_issues

Parent is “text” while the other two are “textarea”

The code at present is:

<td><?php echo $EM_Booking->person->get_name() ?></td>
			<td><?php echo $EM_Booking->person->user_email ?></td>
			<td><?php echo $EM_Booking->person->phone ?></td>
			<td class='spaces-number'><?php echo $EM_Booking->get_spaces() ?></td>
			<td><?php echo $EM_Booking->booking_comment ?></td>

Would anyone know how I might do that? Thanks.
