You can call print() multiple times in your code, resulting in the files being printed one after the other:

function PrintAll() {
    var pages = ["page1.pdf", "page2.pdf", "page3.pdf"];
    for (var i = 0; i < pages.length; i++) {
        var oWindow = window.open(pages[i], "print");
        oWindow.print();
        oWindow.close();
    }
}

Either do as Shodow Wizard suggests and print out the files sequentially or concatenate the files server-side.

You could make an ajax request with the fine names that the user wants to print, concatenate them server side, return the concatenated pdf and then print that out. The concatenation implementation would depend on what server-side language you are using.
