I AM NEW AND LEARNING BUT SO FAR IT IS GREAT. EVEN IF I ONLY PRINT A FEW FORMS A MONTH THE SMALL PRICE IS WORTH THE CLEANESS OF THE FORM. I HAVE BEEN HAND WRITING THEM AND USING WHITE OUT.. I AM GLAD FOR THE SHARPNESS OF THIS AND EASY TO FIND FORMS ..
Anonymous Customer
Good but very expensive; if I could open and fill PDFs on my computer, I would do so, but my computer, for whatever reason, will not allow me to. Also, lining up the characters/text could be better?? But thank you - it's still a lifesaver!
Karen C
An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC
