PDF of a very long form is not outputed correctly

I know how to get a good PDF of a submission that includes text and headers.  But I need a PDF of a blank form so I can mail that to my clients or have them download it from my website.  The text is sometimes hidden and sometimes overlapping other questions.  I realize some of the widgets can't be put in a PDF, but I thought ordinary text, text boxes and that sort of thing was mastered.  

My Tax Organizer form is a very long form; about 14 pages.  Does that make a difference?  I have a shorter form and am not experiencing these issues.  Please help.

You are correct about the long form being the issue. Usually when you have a very long Text element it could cause issues, but if the form itself is too long there will definitely be some issues with it.

I would recommend taking a look at this guide: Fillable PDF - Everything you need to know about JotForm fillable PDF creator

It will show you several known facts about the fillable PDF that you must know, but this also applies to the regular PDF file, at least at this time.

What I would recommend is to either split the form into several segments if you need to print it or save as PDF.

Unfortunately I can not give you any estimate if our developers would increase the size of the forms that can be turned to PDF (issues removed with such long forms) or if they would not, and if they would at what time so for now, only the above options would apply.

I would however like to mention that today, PDF is less likely to be opened and filled out without any issues than a web form since most devices and transportation vehicles have some form of internet available and as long as you have internet and a browser, web form can be filled out, while PDF requires specific software to run to be able to view and fill it out.
