Druckbeleg mit dynamischer Höhe von printDocument C#

Question

Ich verwende Visual Studio 2012 zum Erstellen und Drucker: EPSON TM-T88IV Empfang zu drucken. habe ich ein Printdocument und hier ist mein Code:

public void print_ticket(string service){ 

    int pos = Array.IndexOf(x_service_print_key, service); 

    // Nếu phím bấm tồn tại để kích hoạt in phiếu 
    if (pos > -1) 
    { 
     string printer_code = "1"; 
     string service_code = x_service_code[pos]; 
     string priority = x_priority[pos]; 
     string number = (Convert.ToInt32(x_serial_number[pos]) + 1).ToString().PadLeft(x_serial_number[pos].Length, '0'); 

     // Lấy số cuối cùng của dịch vụ cộng thêm 1 và gán cho biến number 
     string sql = "SELECT number FROM current WHERE service_code = '"+x_service_code[pos]+"' ORDER BY id DESC LIMIT 1"; 
     MySqlCommand cmd = new MySqlCommand(sql, connection); 
     cmd.CommandTimeout = 60; 
     DbDataReader reader = cmd.ExecuteReader(); 
     if (reader.HasRows) 
     { 
      while (reader.Read()) 
      { 
       number = (Convert.ToInt32(reader.GetValue(reader.GetOrdinal("number"))) + 1).ToString().PadLeft(x_serial_number[pos].Length, '0'); 
      } 
     } 
     reader.Close(); 

     // Insert vào database số mới. 
     sql = "INSERT INTO current(printer_code, service_code, priority, number) VALUES('" + printer_code + "','" + service_code + "'," + priority + ",'" + number + "')"; 
     cmd = new MySqlCommand(sql, connection); 
     int rowCount = cmd.ExecuteNonQuery(); 

     // Cập nhật ra màn hình 
     this.Controls.Find("lbl_" + x_service_code[pos].ToString(), true).FirstOrDefault().Text = number; 


     // In phiếu ra giấy 
     printTicket.PrintPage += (sender, e) => 
     { 
      e.Graphics.Clear(Color.White); 
      // Khai báo thông số text 
      // -- Màu sắc 
      SolidBrush drawBrush = new SolidBrush(Color.Black); 
      // -- Font chữ, size chữ 
      Font drawFont1 = new System.Drawing.Font("Arial", 12, FontStyle.Bold); 
      Font drawFont2 = new System.Drawing.Font("Arial", 60, FontStyle.Bold); 
      Font drawFont3 = new System.Drawing.Font("Arial", 16, FontStyle.Bold); 
      Font drawFont4 = new System.Drawing.Font("Arial", 10, FontStyle.Italic | FontStyle.Bold); 
      // -- Căn giữa 
      StringFormat drawFormat = new StringFormat(); 
      drawFormat.Alignment = StringAlignment.Center; 

      // Logo 
      Image imgLogo = QMSBUTTON.Properties.Resources.p_logo; 
      e.Graphics.DrawImage(imgLogo, 20, 0, 280, 24); 
      // Khoa khám bệnh 
      RectangleF recAtZero = new RectangleF(0, 25, e.PageBounds.Width, e.PageBounds.Height); 
      e.Graphics.DrawString("KHOA KHÁM BỆNH", drawFont1, drawBrush, recAtZero, drawFormat); 
      // Số thứ tự 
      recAtZero = new RectangleF(0, 50, e.PageBounds.Width, e.PageBounds.Height); 
      e.Graphics.DrawString(number, drawFont2, drawBrush, recAtZero, drawFormat); 
      // Tên dịch vụ 
      recAtZero = new RectangleF(0, 150, e.PageBounds.Width, e.PageBounds.Height); 
      e.Graphics.DrawString(x_service_name[pos], drawFont3, drawBrush, recAtZero, drawFormat); 
      // Phiếu in lúc 
      recAtZero = new RectangleF(0, 180, e.PageBounds.Width, e.PageBounds.Height); 
      e.Graphics.DrawString("Phiếu in lúc: " + DateTime.Now.ToString("HH:mm:ss - dd/MM/yyyy"), drawFont1, drawBrush, recAtZero, drawFormat); 
      // Phiếu chỉ có giá trị trong ngày! 
      recAtZero = new RectangleF(0, 200, e.PageBounds.Width, e.PageBounds.Height); 
      e.Graphics.DrawString("Phiếu chỉ có giá trị trong ngày!", drawFont4, drawBrush, recAtZero, drawFormat); 


     }; 

     printTicketDialog.ShowDialog(); 
     //printTicket.Print(); 
    } 
} 

Das Problem ist, wenn ich drucken, die Höhe der Seite so lang ist und nicht direkt nach dem Fertig Dokument abgeschnitten. Ich brauche es dynamisch nach dem letzten Zeichnungstext zu schneiden.

Sorry für mein schlechtes Englisch. Vielen Dank!

Answer 1

// Add list of supported paper sizes found on the printer. 
// The DisplayMember property is used to identify the property that will provide the display string. 
comboPaperSize.DisplayMember = "PaperName"; 

PaperSize pkSize; 
for (int i = 0; i < printDoc.PrinterSettings.PaperSizes.Count; i++){ 
    pkSize = printDoc.PrinterSettings.PaperSizes[i]; 
    comboPaperSize.Items.Add(pkSize); 
} 

// Create a PaperSize and specify the custom paper size through the constructor and add to combobox. 
PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200); 

comboPaperSize.Items.Add(pkCustomSize1);

Answer 2

fand ich die Art und Weise:

PaperSize pageSize = new PaperSize(); 
pageSize.Width = 284; 
printDocument.DefaultPageSettings.PaperSize = pageSize; 

Set papeSize auf Printdocument, aber nur Breite festgelegt, nicht nicht gesetzt Höhe. Der printDialog wird seltsam aussehen, aber der Drucker ist korrekt.
