[RESOLVED] Building a Windows Printer Driver

I need a really small printer for a particular purpose. Although I have found one for sale it does not come with a Windows compatapible driver. So, before I purchase said printer, how do I build my own driver for it? What specific info do I need from the manufacturer, etc.? Or am I just wasting my time and effort and should search for something else? I would prefer if I could build it so that it is compatible with all Windows platforms (3.x, Win 95/98 and maybe even DOS).
