Well, I think this may be an interesting challenge. I would like to collect data in a datalogger and genarate a pdf report in the datalogger micro itself. The otput would be a .pdf file stored in my SD-card. This is a task for a micro and the search is for some pdf generator library in " C ". I am an exelent coder and all of the other parts of the design I already know very well, including generating a file in my sd-card. Any code? In advance!
Write simple HTML. And let the user print it from the browser if needed - free PDF printers are available too for all platforms.
And never write "I am excellent" in a forum.
Programming has earned me a living for more then 2 decades ... but I would never write sth like that - because I am aware that I always make mistakes and there are always others around being better...
