I am not a Win32::API expert, but I think I can help interpret that (in case someone else is reluctant to try, based on your historical reluctance to try):

my $shellopen = new Win32::API(
    "shell32", "ShellExecute",
    ['N', 'P', 'P', 'P', 'P', 'I'],
    'N'
    );

 This uses the IMPORTING A FUNCTION BY PROTOTYPE feature of Win32::API to set up a wrapper for the Windows API function ShellExecute() from the shell32.dll
$shellopen->Call(0, "print", $pdf, 0, 0, 0); This calls the "print" verb defined in the Windows registry. This is the same as right-clicking on the file and selecting Print from the context menu in Windows Explorer.
