Since 1999, Two Pilots' focus has been software development. One of its first software products was Form Pilot - a form-filling program that allows users to fill out forms on a computer instead of using a typewriter. Form Pilot used a virtual printer for transferring the form image to the program window. The team developed the virtual printer driver for the Form Pilot software. Quite quickly virtual printer development grew into a standalone service. However there were limitations in the enhancement of Two Pilots' products caused by using an external PDF library.
