I need a non-interactive replacement for PrintDlg

I am extending an existing program which uses some various Windows printing API calls. I select the printer with PrintDlg, start a document with StartDoc, Close it with EndDoc, control pages with StartPage and EndPage and do text and graphics with TextOut, Rectangle, MoveToEX, LineTo, etc.. The program runs on Windows 2000, Windows XP, and Windows 2003 Server.

My problem is that I need to extend the program to print to another printer in a way that is invisible to the user of the program. The modified program will print one copy of the output to the printer selected by PrintDlg, and another copy to another printer which is selected with no user input whatsoever. I need a non-interactive substitute for PrintDlg that will let me use the rest of my printing stuff unchanged.

(Note that I am actually writing in Ada, not C, but any answers I get should probably best be expressed in terms of plain C, as I can easily translate.

Well, your replacement fot that API is - 'PrintDlg()'. Or better, the PRINTDLG struct filled in by your first interactive call to that function. You'd use make a copy of that struct and then alter the respective members (hDevMode, hDevNames and hDC) to represent the other printer you want to send your output to.

CreateDC does indeed work for what I need to do. The core of the thing is in the attached snippet.
type Pointer_To_DEVMODE is access all DEVMODE;
    type Pointer_To_char is access constant Interfaces.C.char;
    
    function CreateDC (
      lpszDriver: Pointer_To_char;
      lpszDevice: Pointer_To_char;
      lpszOutput: Pointer_To_char;
      lpInitData: Pointer_To_DEVMODE
    )
      return GWindows.Types.Handle;
    pragma Import(StdCall, CreateDC, "CreateDCA");
