I want to make scale up the panel with picture box, textbox, and label following the print page but scale up only panel not with picture box, textbox, and label. Can you help me to finish it.

What I have tried:

public partial class Form1 : Form
   {
       Bitmap memoryimg;
       PrintPreviewDialog printprvw = new PrintPreviewDialog();
       PrintDocument printdoc = new PrintDocument();
       Panel pannel;

       public Form1()
       {
           InitializeComponent();
       }
       private void button1_Click(object sender, EventArgs e)
       {
           panel1.Size = new Size(794, 1123);
           Print(this.panel1);
       }

       private void Print(Panel pn1)
       {
           PrinterSettings ps = new PrinterSettings();
           pannel = pn1;
           getprintarea(pn1);
           printprvw.Document = printdoc;
           printdoc.PrintPage += new PrintPageEventHandler(pntdoc_printpage);
           printprvw.ShowDialog();
       }

       private void pntdoc_printpage (object sender, PrintPageEventArgs e)
       {
           Rectangle pagearea = e.PageBounds;
           e.Graphics.DrawImage(memoryimg, 0,0);
       }

       private void getprintarea(Panel pn1)
       {
         memoryimg = new Bitmap(pn1.Width, pn1.Height);
         pn1.DrawToBitmap(memoryimg, new Rectangle(0,0,pn1.Width,pn1.Height));
       }

   }
}

You first need to get the dimensions of all your controls, and the spacing between them. Then get the dimensions of the page that you are going to print on. From there you can calculate whether you need to scale up or down on the final page. Try making a drawing on a piece of paper to visualise what you need to do.
