No.

Why would you want to print the contents of the hard drive?

God forbid.
If that were possible, you'd probably get a picture of naked women every
hour or so on the 'net. (depending on your interests).

What does this control character do? If it's a page break, there's something
in css. If not, please describe it further.

I wouldn't.

This DOS command ... echo ^G > LPT1 ... will send a chr(7), or BEL character
to a receipt printer I have connected to the clients PC. There is an
electronic cash drawer connected to the receipt printer. When the receipt
printer receives a chr(7)/BEL character, it kicks the cash drawer open.

I have tried sending chr(7) to the printer, but all it does is actually
print the little ASCII character, rather than ringing the BELL and opening
the drawer.

However, if I do exactly the same thing in DOS, the drawer opens correctly.

Therefore I need to perform a wscipt.shell command or equivilent to perform
the DOS function. I have tried every variation of the wscript.shell
command, and it won't run either a DOS batch file or a VBS script file.

I have scanned the web and this question is asked all over the place, but no
one seems to have a solution.

You definitely can't do that from a web page. As pointed out before: if you
could use an eqivalent of the shell() function, you could do _anything_ on
the user's computer.

I see. You might try using cgi then or perhaps even php.
To my knowledge, you can not activate a dos command in html by itself.
If you're not needing to go online, and be purely local with the routine,
how about using a language called libertybasic?
www.libertybasic.com
It's basic, but designed to work with windows without leaving windows.
It has all the features of BASIC, plus some other goodies to make it more
applicable for writng stuff like games in windows.
The free version doesn't allow you to create "exe" files but for a small fee
you can get that.

If the HTML page is hosted on a local web server (i.e. the cash register
thing is directly attached to the web server) then you should be able to
to this pretty easily with server-side scripting.

Um... a grocer selling pickles and running Apache?
Could be sommething different, though

Why not? If there's already a computer there it's a short step to
installing a web server on it. Most POST terminals run some operating
system and have a shell, so compiling such software would be a
reasonably trivial task.

Set WScript = CreateObject("WScript.Shell")
WScript.Exec("C:\Windows\Command.com /C Echo ^G > LPT1")
:fight:
Exit

This will send the character to your printer. Whether it beeps or not I cannot predict!
