Compatible with v2?

Should this work with v2? As far as I understand I need to change directory from order_action to order, and class from oa to om. After that I can configure settings but I can't find pdf invoices itself. Should it work or  am I missing something?
I have updated the add-on. See if it makes your clock tick.
Great! That's great service Tim. Thanks :)
Does it support other characters than Windows-1252? It shows ? intead.
Sorry this is a limitation of FPDF.

I found a thread regarding this on stack overflow:
