Overall it is pretty good, however, it is blurry when I print my page and I could not read it clearly. Can someone send me information on what I can do to make this better. Send answer to hickshayes@gmail.com. Thank you.

I was printing IRS form 1099-MISC and wish there was a way I could have copied all info from the first page to the subsequent pages, but there wasn't.

It was easy enough to use the first time I tried. I was able to fill out my 1099's within a couple hours and file them with the IRS. It was so simple! I appreciate your service.

Excellant! I am an insurance Broker My forms are stored and I can retype the information for the up coming renewals with applications for Insurance both Liability and Property and Specialty insurance I would like that PDFiller would have a storage data for my forms that I can go back to each year for each of my clients and update for the new year, thus redosing my retyping of information on the Acord Form.

I ordered the yearly subscription… I ordered the yearly subscription instead of monthly and was easily able to fix this via the chat box on their website! Great customer service!

So far this program is a game changer. I wish it was cheaper (a discount for teachers on a year subscription would be wonderful!!) but I like what I am seeing so far;)
