You have to carefully choose where to type, the format functions are limited and the printing is a little awkward as you cannot alter the margins. However, it is easy to use.

The program interface is OK but it could be a little more iterative. A form I was completing for the TSP TP77 and the TP76 did not place the letters and numbers (characters) in the exact center of each box making the document a little harder to read. I know this for sure because I have completed the same document using TSP website filler with the document are available. This would be easy for the company to fix this but they check their forms before making them available. But the overall online forms filler program works well and saves completed forms easily and has a generous library.

Some functions are not readily apparent but overall it is a great tool. I had difficulty when it auto-filled a date field that I wanted to leave blank. I struggled to clear it because the dropdown appeared every time I tried, and if I deleted the current date got restored by the dropdown. Then after I finally blanked the field it jumped to another and did the same thing. Once I got that cleared it would not let me go to the next page, insisting I populate another field intentionally left blank. I used the slider to jump forward and then approach the page I wanted from the other direction.
