I had a little issue trying to find out how to print the form. Also, the little movable box that kept showing me where to check got in the way of reading the document. I X'ed it out most of the time so I could read the instructions.

What do you like best?
It's simple and easy. I can pull forms from the internet, email, my desktop, etc and fill them in for a professional look.
What do you dislike?
The printing process could be laid out a little more simply. It works well; but a little 'clumsy' vs smooth like printing in microsoft products.
Recommendations to others considering the product:
It an efficient product that makes all documents/applications/etc look professional.
What problems are you solving with the product? What benefits have you realized?
Completion of all business forms look professional. We've eliminated handwritten credit applications. It's efficient to create and especially for credit applications, we save the prior information there so easy to update.
