Most of my customer are now using PDF-Creator for making PDF files and emailing them. It is a great easy alternative and "green way" to printing and snail mailing your invoice or letters. Just Install PDF-Creator and you can be printing PDF files the easy way! On Kauai and Maui most of my non-profit companies that I service uses PDF-Creator. So for those that keep asking me about Adobe Acrobat, I tell them to buyPDF-Creator.
