Huh

I've just 'printed' some reports using the print button on the print preview toolbar, but none of them came out of my printer.

The NUL device is a virtual device from the operating system.
In the DOS years you could use it to pipe screen output to it.

Probably it don't work under NT machines

What you can do then is instead of outputting to the NUL device, outputiing to a temporary file. Just replace NUL with yourtempfile.tmp and try again.
Please let me now if that works.
Evan asked me to send this as a new FAQ item, so i can use every information you give me.
