using to email invoices ?

[Stuart]

Hi, i am new to this program and after reading the write ups etc have downloaded primopdf in the hope of being able to email invoices. I am unable to see whether i can do what i need though. Will this program let you save a template ie my headed invoice paper and print invoice onto this template? Obviously i then need to email it, is there an easy way.
Many thanks and sorry if this sounds dumb, may be the wrong program for me. Please prove me wrong.
