printing - Format Print Document in C# -

I am quite new to c # and need some help in creating a document for printing.

I have already been able to talk to the printer through this code:

  Private Zero Print (String Printer) {PrintDocument PrintDoc = new PrintDocument (); PrintDoc.PrinterSettings.PrinterName = Printer; PrintDoc.PrintPage + = New PrintPage event handler (printpage); PrintDoc.Print (); } Zero printpase (Object Sender, PrintPage Event Eg) e.Graphics.DrawLine (New Pen (Color. Black), New Point (0, 0), New Point (100, 100)); E.Graphics.DrawString ("Hello World", New Font ("Times New Roman", 12), New Solidbrush (Color Black), New Point (45, 45)); }   
 Who print my string "Hello World" is obviously the print code of the code which I found on the net. Sadly, I could not find any way for  
 a) Set the size of the paper format that is printed on (this is the 138 mm x 99 mm landscape format)  
 b) Tell the printer where to print my texts properly.  
 This paper is a PRINTMENT form and I have to write my own text in the specific field.  
 I therefore have my own printed document such as:  
   & Lt; Text & gt; Textfield 1 & lt; / Text & gt; & Lt; / Field 1 & gt; & Lt; Field2 & gt; ....   
 I could not find information on how to do this. So if someone can tell me how to do this or have a good tutorial, then I am very thankful   
 
 
 to set the paper size  
  printDocument.DefaultPageSettings.PaperSize = new paper size ("custom name", width, height); PrintDocument.DefaultPageSettings.Landscape = true;   
  Width and height is in the one hundredth of a century   
 See the tutorial in the SO question for print text on pre-printed paper.  
 To avoid paper wastage during your experiment, scan the preprint paper as an image and set it as a background in  PrintPageHanlder  while previewing.  
  void printDocument_PrintPage (Object Sender, PrintPageEventArgs e) {if (printDocument.PrintController.IsPreview) {Image Image = Image.FromFile ("Scanned ImagePath"); E.Graphics.DrawImage (Image, 0,0)} // After printing the background, print the other text here
