Put this on top of all declarations

ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, _
ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

and simply use as

ShellExecute 0&, "open", fileFullPath, 0, "Directory", 0
The question of the original poster was ... PRINT pdf files. So you need to change the "open" command to a "Print" command.
