For CC orders, click "shipped", auto email invoice?

For CC orders, when “shipped” is clicked in Customer Shipment, the packslip gets marked shipped, invoice is created, cc charged, and cash receipt posed.

I’m looking through the trace logs, but am having a hard time figuring out where I could put a hook for these CC orders to also automatically APR email the invoice.

Any ideas?

We want this also! We have APM but would switch to APR to get this functionality.

Use auto print on ShipHead where it’s marked as Shipped.
