i hate to keep asking questions, but :P

1) what are the 2 arguments passed to it ?
my($w, $pinfo) = @_;
i.e. which is the canvas, and what is the other thing ?

2) This appears to use PIPE's ? im using windowsXP, I though pelr couyldnt use pipes outside of linux. Or is that just for the Printer module ?

Thanks again :)
