Mike,
you are in fact asking a hardware question in a software forum. If you have the correct hardware, printing on an envelope is nothing different from printing on a paper.
>We currently have label printing capabilities in our application. It prints to a page of 30 labels (3 across by 10 rows) and works well. Now we've had a request to print directly to envelopes in order to avoid the labels.

>Has anyone done this and care to share their ideas/experiences/code? Can printers stack envelopes like regular paper?
