I just had a go at downloading the drivers and having a play as Control Eng suggested.
Although not having the actual device connected limits investigations slightly, but with the use of Print Preview, it certainly seems like this is probably an efficient achievable way to enable FPS printing, especially if you can get your Excel spreadsheet to be very user friendly.
It would be useful if you could link up your "Obtain PPR" page from your website to automatically print a FPS when someone sends their completed PPR request!
Let us know how you get on at Barton.
I suspect Control Eng has lost some Aviation Software Developers some income world wide!
Well done!
