Just to increase my knowledge, I purchased a textbook on "Building Web Pages" using HTML. Looking at some of the examples in the book and piecing together some 'other' commands I was able to construct a form without using CSS.
It was not the most elegant but very useful. A friend had some knowledge of HTML and also had a code generator application that produced code from drag and drop screen shots. My original code and his tweaking produced a very acceptable fillable form.
A little extra investigating and a button was added to Print the filled out form. Only took about 4 hours from scratch to complete the task.
One thing I did learn was that each browser has their own quirks. Such as, basic Edge does not have a 'File Open' function whereas Firefox does. Also some code reacts differently on each browser. This is pointed out in the text book.

I guess you are never to old to learn a new coding language.
