I asked a similar question (perhaps on another forum) several years ago. I received an answer which I do not understand (and was reluctant to try). It worked great for me. For what it is worth, here is the code which I found on an old backup disk. (It prints a PDF file where $pdf is the name of the file.) 
my $shellopen = new Win32::API(
    "shell32", "ShellExecute", 
    ['N', 'P', 'P', 'P', 'P', 'I'],
    'N'
    );

$shellopen->Call(0, "print", $pdf, 0, 0, 0);

Clearly this only works on windows. I am nearly certain that I have used it on both XP and Windows 7.
