plug-in or script to print unrelated, multiple InDesign files

This is actually a very useful script but when I use the script it doesn't print in the order it is in the folder.

For example. I would have these documents below. It would print document 1, 10 and then 2-9. Would there be an additional line where I would place in the script to make it work?

Document1

Document2

Document3

Document4

Document5

Document6

Document7

Document8

Document9

Document10

So I just wanted to post this script as is b/c it works now. It still lacks a progress bar. And if I'm able, I'll post a revised version with a progress bar. But this will print multiple, separate InDesign files with their last saved print preset.

function createDialog(folder, allFilesList) {
     var d, showDialog, winspec;
 
     winspec = [
     "dialog { orientation: 'column', alignChildren: 'top', text: 'Multiple Print',",
     "  folderPanel: Panel {",
     "    name: 'Files to Print',",
     "    alignment: 'fill',",
     "    StText1: StaticText { },",
     "    StText2: StaticText { }",
     " }, okCancelGroup: Group {",
    "   orientation: 'row', alignment: 'center',",
     " } ",
     "}"].join("");
 
    d = new Window(winspec);
     d.folderPanel.StText1.text = myFolder.fullName;
     d.folderPanel.StText2.text = '(Found ' + myAllFilesList.length + ' files)';
     d.okCancelGroup.add('button', undefined, 'Go', { name: 'ok' } );
     d.okCancelGroup.add('button', undefined, 'Cancel', { name: 'cancel' } );
 
    showDialog = d.show();
     $.writeln("s"+showDialog);
     return showDialog;
}

var InDesignVersion=app.version.split(".")[0]

var myFolder = Folder.selectDialog();
if (!myFolder) exit();
var myAllFilesList = myFolder.getFiles("*.indd");

if (!myAllFilesList.length) {
     alert("No files to print.");
     exit();
}

var myDialogResult = createDialog();
if (myDialogResult == 2) {
     exit();
}

var i, f, files, uil;
 
suil = app.scriptPreferences.userInteractionLevel;
app.scriptPreferences.userInteractionLevel =
  UserInteractionLevels.neverInteract;
 
try {
  files = myFolder.getFiles("*.indd");
  app.print(files);
} catch (e) {
  alert("Caught error:" + e);
} finally {
  app.scriptPreferences.userInteractionLevel = uil;
}

This is so close. The dialog box comes up, but whether I hit "go" or "quit", or even if I try escape, the script proceeds anyway. Kind of defeating the point of the dialog box.

I tried adding in an if satement like the one from the PDF, but it freezes up at the dialog box and hitting "go" or "quit" does nothing, and I cannot escape out fo the script.

if (myDialog.show() ==1)
var myShowDialog = myDialog.show();

return myShowDialog;

I'm thinking it should be something besides "myDialog.show" but i'm not sure what.

This is certainly easy to script. Untested (so it probably needs a little help):

var folder = new Folder("/path/to/folder-of-files");
var i, f, files, uil;
uil = app.scriptPreferences.userInteractionLevel;
app.scriptPreferneces.userInteractionLevel =
  UserInteractionLevels.neverIntact;
try {
  files = folder.getFiles("*.indd");
  app.print(files);
} catch (e) {
  alert("Caught error:" + e);
} finally {
  app.scriptPreferences.userInteractionLevel = uil;
}

Since allegedly app.print() takes an array of files, it might well be the case that you're better off looping through the array of files and printing each one at a time, since that way you can find out when something goes wrong. Or possibly even opening the files and then printing them and closing them, one by one. But each of those is more work. So try the above.

It, of course, expects the files to be in a folder of their own, /path/to/folder-of-files. So change that.
