Check my modification in my last post, Webbrowser was placed in appwin style part of the code, should be in the path part.
You may get a dll error, in which case, change system to system32
so
[php]
Shell("rundll32.exe C:\WINDOWS\SYSTEM32\MSHTML.DLL,PrintHTML Webbrowser.url", vbMinimizedFocus)
[/php]
