Show customer Email address in printable order copy?

Is it possible to display an email address of the customer on the printable order copy?

I thought it is litecart so I simply adjust the display of the address in the country and add %customer_email, but unfortunately that was too simple. That doesn't work for me.

Is there another way to easily add this?

Thanks, that works.
