So far printing doesn't work when printing directly from filled in form. I need to save it to my desktop and open in my pdf application and print from there.

I don't need legal documents very often & purchased to help a friend get through a difficult time. much better than hand writing all of the documents out. makes it look professional and I will probably use in the future as well, if needed.

Saving me so much paper and I'm feeling really positive about my environmental impact. We are in the process submitting our B Corp assessment and this product has highlighted that with some thought you can make small differences

Love it- so easy- wish there was a cheaper option for "stay at home moms" (could verify with a phone call) - since all I tend to use it for is school forms and household paperwork

Managing the signature was difficult and took many attempts. Something near satisfaction was accepted. Otherwise, this app saved me time and made this task easier to complete. Thanks to PDFfiller.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.
