Drupal Commerce: Print order?
Through Rules module you can achieve this:


First step create a custom rule at /admin/config/workflow/rules/reaction/add
Select the React on event: "Completing the checkout process"
Add a new Action: "Send mail"
Once you add the email addresses from/to, than add the replacement fields in the body text of the email. I suggest: [commerce-order:order-number], [commerce-order:type], [commerce-order:commerce-line-items]. But you can figure that part out.


Save your Rule. 

Get a Beer and celebrate you are now forwarding new orders to your customer fulfillment department.
