Close Adobe Reader after printing document

I am using the following ShellExecute command to print a PDF document which works a treat but it leaves the Adobe reader program open on the task bar. How can i close this program in script?

My Code

    fname = "C:\Temp\fms52703.pdf"

Dim hwnd As Long

Dim ret As Long

Dim lngresult As Long

	

ret = ShellExecute(hwnd, "Print", fname, "", "", 0)

Subject: I think there is a /t switch you can use
