very thanks Cal.

I don't have any problem with security settings or another client side
setting. Because actually I'm using PHP for an application (but not a web
application) just works for the machine which is the server or in the same
LAN with the werver. And all settings of their browsers are made by me. So
that i can make all settings  proper to do so. Also OS is win98 or maybe
win2000. Most scanner's user interfaces can absolutely do their job perfect
on scanning and sending the output to the caller. But the only problem here
I understand is that it's not possible to call an EXE file?
