How to print a very long Ticket using PrintDocument

I'm trying to print a ticket on a thermal printer, the information that the ticket must contain is enough so the ticket has a considerable length. I'm using a PrintDocument object to print the ticket, in the PrintPage event I use a Graphics object to write all the information. When printed the ticket appears correctly, the problem is that it is not printed completely. Is there a way to indicate the size of the print and so the ticket can be printed out completely?

PrintDocument printDocument = new PrintDocument();
        printDocument.PrinterSettings.PrinterName = impresora;            
        printDocument.PrintPage += new PrintPageEventHandler(this.pr_PrintPage);
        printDocument.Print();

This is the PrintPage event:

    private void pr_PrintPage(object sender, PrintPageEventArgs e)
    {
        e.Graphics.PageUnit = GraphicsUnit.Millimeter;            
        this.gfx = e.Graphics;
        this.DrawHeader();
        this.DrawItems();
        this.DrawTotales();
        this.DrawFooter();            
    }

for the "Draw" methods I am using the DrawString function of the Graphics object (gfx).

You can specify the size of the page to print indicating the PaperSize in the property DefaultPageSettings of PrinterSettings in the following way:

int width = 100; //Indicar el ancho de la pàgina
int height = 100; //Indicar el alto de la pàgina

PrintDocument printDocument = new PrintDocument();
printDocument.PrinterSettings.PrinterName = impresora;
printDocument.PrinterSettings.DefaultPageSettings.PaperSize = new PaperSize("Nombre a poner a esta configuración", width, height);
printDocument.PrintPage += new PrintPageEventHandler(this.pr_PrintPage);
printDocument.Print();
