C＃从右到左打印

我正在处理一些阿拉伯数据，我想从右到左打印

我试过了

StringFormat format = new StringFormat(StringFormatFlags.DirectionRightToLeft);
                e.Graphics.DrawString(dataToPrint, valueFont, System.Drawing.Brushes.Black, 20, 20, format);

但这使文本仍然从左开始，并且变得更糟，所以现在我看不到所有这样的文本：

但是，当我删除时format，我得到了：

我需要与第二张图片完全一样，但从右到左。

有什么帮助吗？

更新1这就是我填充dataToPrint对象的方式

 System.Drawing.Font valueFont = new System.Drawing.Font("Arial", 15, System.Drawing.FontStyle.Regular);
                string dataToPrint = "";
                dataToPrint += "رقم بطاقة التسويق = " + farmID.Text + Environment.NewLine;
                dataToPrint += "إسم صاخب المزرعة = " + farmOwner.Text + Environment.NewLine;
                dataToPrint += "رقم المزرعة = " + farmNumber.Text + Environment.NewLine;
                dataToPrint += "الموبايل = " + farmMobile.Text + Environment.NewLine;
                dataToPrint += "الإمارة = " + emaraNameArabic.Text + Environment.NewLine;
                dataToPrint += "المنطقة = " + areaNameArabic.Text + Environment.NewLine;
                dataToPrint += "الإقليم = " + regionNameArabic.Text + Environment.NewLine;
                dataToPrint += "مركز الإستلام = " + receivingCenterName.Text + Environment.NewLine;
                dataToPrint += "خلاص = " + khalas.Text + Environment.NewLine;
                dataToPrint += "فرض = " + fardh.Text + Environment.NewLine;
                dataToPrint += "لولو = " + otherLulu.Text + Environment.NewLine;
                dataToPrint += " خنيزي= " + khedrawi.Text + Environment.NewLine;
                dataToPrint += "بومعان = " + boumaan.Text + Environment.NewLine;
                dataToPrint += "برحي = " + barhi.Text + Environment.NewLine;
                dataToPrint += "جش خزمة = " + jeshKharma.Text + Environment.NewLine;
                dataToPrint += "رزيز = " + reziz.Text + Environment.NewLine;
                dataToPrint += "جبري = " + jabri.Text + Environment.NewLine;
                dataToPrint += "عنبرة المدينة = " + anbaretAlMadina.Text + Environment.NewLine;
                dataToPrint += " شيشي= " + shishi.Text + Environment.NewLine;
                dataToPrint += "دباس = " + dabbas.Text + Environment.NewLine;
                dataToPrint += "نبتة سيف = " + nabtetSaif.Text + Environment.NewLine;
                dataToPrint += "خضراوي = " + khedrawi.Text + Environment.NewLine;
                dataToPrint += "هلالي = " + hilali.Text + Environment.NewLine;
                dataToPrint += "مكتومي = " + maktoumy.Text + Environment.NewLine;
                dataToPrint += "نميشي = " + namishi.Text + Environment.NewLine;
