如何在Metro风格的应用程序中选择打印机

Question

I'm trying to convert an existing desktop app into metro style app (Win8 & VS12). but i'm having a hard time dealing with the printing.

my software has two users - "Admin" and "User". I want the "Admin" to be able to choose printer and printer settings, and the "User" need to press on "Print" button, and that's it.

the troubles are:

1. I can't find how to get all connected printers. ( DeviceInformation.FindAllAsync() requires DeviceClass which has these options only - All, AudioCapture, AudioRender, PortableStorageDevice, VideoCapture ). [in my original app (WPF), i'm using PrinterSettings.InstalledPrinters ]

2. I can't find a way to print to a selected printer (even if I already know the name). since (as far as i understand), the only way to print is to open (using code or registration) the "charms" bar, and let the user to choose the printer. What if i don't want the user to use a specified printer ?

3. Is there a way to reference a "normal" C# dll that will do the "dirty stuff" for the metro-style app ? When i'm trying, i'm getting "Unable to add reference to project 'Try1'". is there's a way to bypass it ?

thank you very much in advance !

Printing in a Windows Store app is now handled by a task . You don't have to do all the work of finding the printers and making the user select one, that's now handled by Windows.
