Using Resident Font

Question:

Instead of printing graphics, how can I get TPrinter to use the default resident font in the printer?

Answer:

Use the Windows API function GetStockObject() to retrieve the
device default font handle, and assign it to Printer.Font.Handle.

Example:

uses Printers;

procedure TForm1.Button1Click(Sender: TObject);
var
  tm : TTextMetric;
  i : integer;
begin
  if PrintDialog1.Execute then begin
    Printer.BeginDoc;
    Printer.Canvas.Font.Handle := GetStockObject(DEVICE_DEFAULT_FONT);
    GetTextMetrics(Printer.Canvas.Handle, tm);
    for i := 1 to 10 do begin
      Printer.Canvas.TextOut(100,
                             i * tm.tmHeight +
                             tm.tmExternalLeading,
                             'Test');
    end;
    Printer.EndDoc;
  end;
end;
