Answer 1

Procedure StrLstYazdir(pYazilacakListe: TStringList; pYazici: String);
var
  hPrn: THandle;
  yazilacakVeri: AnsiString;
  intA: Integer;
begin
  hPrn := StartRawPrintJob(PChar(pYazici), '', 'Varakim');
  if (Integer(hPrn) < 0) then
  Begin
    ShowMessage('StartRawPrintJob Hatalı');
    Exit;
  End;

  if (StartRawPrintPage(hPrn) < 0) then
  Begin
    ShowMessage('StartRawPrintPage Hatalı');
    EndRawPrintJob(hPrn);
    Exit;
  end;

  For intA := 0 to pYazilacakListe.Count - 1 do
  Begin
    yazilacakVeri := pYazilacakListe[intA] + #13 + #10;

    if (PrintRawData(hPrn, PAnsiChar(yazilacakVeri), Length(yazilacakVeri)) < 0)
    then
    begin
      ShowMessage('PrintRawData Hatalı');
      EndRawPrintPage(hPrn);
      EndRawPrintJob(hPrn);
      Exit;
    End;
  End;
  if (EndRawPrintPage(hPrn) < 0) then
  begin
    ShowMessage('EndRawPrintPage Hatalı');
    EndRawPrintJob(hPrn);
    Exit;
  End;

  if (EndRawPrintJob(hPrn) < 0) then
  begin
    ShowMessage('EndRawPrintJob Hatalı');
    Exit;
  End;
End;

Usage:

StrLstYazdir(Memo1.Lines ,'Lexmark Forms Printer 2491')
