Yes, I think, maybe.
You can use cfexecute to send output to printers recognized
by the server. I know that part is true because I have done it.
This is useful in intranet worlds where I work but probably rather
quite useless for the internet.
Plus, I'm not sure if flashpaper is what you want. If you
used pdf instead, you might be able to create a file and use
cfexecute to print the file. This part I'm not quite as sure about.
Read the part about cfdocument in the cfml reference manual and
you'll know whether or not you can create a file.
