Today we are going to focus on printing from Windows Form application silently to the printer using C# graphics object. Graphics objects are defined from:
- Namespace: System.Drawing
- Assembly: System.Drawing.dll
Get More on
Let’s get started by creating a new sample windows form application. Here is how we have structured the application.
Form:
public partial class FrmPrint : Form
{
private List data = null;
private PrintTemplate objPrintTemp = null;
public FrmPrint()
{
InitializeComponent();
}
private void FrmPrint_Load(object sender, EventArgs e)
{
chkPrintPrv.Text = "Print Preview";
}
private void btnPrint_Click(object sender, EventArgs e)
{
try
{
data = new List();
data = CartData.GetData();
new Print(data).PrintDoc();
}
catch (Exception)
{
throw;
}
}
private void chkPrintPrv_CheckedChanged(object sender, EventArgs e)
{
try
{
if (chkPrintPrv.Checked)
{
chkPrintPrv.Text = "Generated Preview";
PrintPreviewControl ppc;
PrintDocument docToPrint = new PrintDocument();
PaperSize psize = new PaperSize("Custom", 280, 300);
ppc = new PrintPreviewControl();
ppc.Name = "PrintPreviewControl1";
ppc.Dock = DockStyle.Fill;
ppc.Location = new Point(0, 0);
ppc.Document = docToPrint;
ppc.Zoom = 1;
ppc.Document.DocumentName = "c:\\";
ppc.UseAntiAlias = true;
ppc.Margin = new Padding(0);
ppc.BackColor = Color.White;
ppc.Document.DefaultPageSettings.PaperSize = psize;
ppc.Document.PrintController = new StandardPrintController();
tpanelRptPrev.Controls.Clear();
tpanelRptPrev.Controls.Add(ppc, 0, 0);
objPrintTemp = new PrintTemplate();
new PrintTemplate(CartData.GetData());
docToPrint.PrintPage += new PrintPageEventHandler(objPrintTemp.Default_Receipt);
docToPrint.Dispose();
}
else
{
chkPrintPrv.Text = "Print Preview";
tpanelRptPrev.Controls.Clear();
}
}
catch (Exception)
{
throw;
}
}
}
Models:
public class vmItems
{
public int ItemId { get; set; }
public int ItemQty { get; set; }
public string ItemName { get; set; }
public double ItemPrice { get; set; }
public double ItemTotal { get; set; }
public List vmChildItems { get; private set; }
public vmItems(int id, int qty, string name, double price, double total)
{
ItemId = id;
ItemQty = qty;
ItemName = name;
ItemPrice = price;
ItemTotal = total;
vmChildItems = new List();
}
}
Data:
public class CartData
{
public static List GetData()
{
List data = null;
try
{
var Item1 = new vmItems(1, 2, "Chicken Tikka", 3.50, 7.00);
var Item2 = new vmItems(2, 1, "Kebab", 3.50, 3.50); Item2.vmChildItems.Add(new vmItems(1, 2, "Extra Hot", 1.50, 1.50));
var Item3 = new vmItems(3, 3, "Chicken Masala", 3.50, 3.50);
var Item4 = new vmItems(4, 1, "Faluda", 3.50, 3.50);
data = new List { Item1, Item2, Item3, Item4 };
}
catch (Exception)
{
throw;
}
return data;
}
}
Print:
public class Print
{
private PrintDocument pdoc = null;
private PrintTemplate objPrintTemp = null;
private static List cartData = null;
public Print()
{
}
public Print(List data) : this()
{
cartData = data;
}
public void PrintDoc()
{
try
{
objPrintTemp = new PrintTemplate();
using (pdoc = new PrintDocument())
{
PrintDialog pd = new PrintDialog();
PrinterSettings ps = new PrinterSettings();
PaperSize psize = new PaperSize("Custom", 280, 900);
pd.Document = pdoc;
pd.Document.PrintController = new StandardPrintController();
pd.Document.PrinterSettings.PrinterName = Printer.GetDefaultPrinter();
pd.Document.PrinterSettings.Copies = 1;
pd.Document.DefaultPageSettings.PaperSize = psize;
pdoc.DefaultPageSettings.PaperSize.Height = 900;
pdoc.DefaultPageSettings.PaperSize.Width = 280;
new PrintTemplate(cartData);
pdoc.PrintPage += new PrintPageEventHandler(objPrintTemp.Default_Receipt);
//Print to Printer
PrintPreviewDialog pp = new PrintPreviewDialog();
pp.Document = pdoc;
pdoc.Print();
pdoc.Dispose();
}
}
catch (Exception)
{
throw;
}
}
}
Print Templating:
public class PrintTemplate
{
private static List cartData = null;
public PrintTemplate()
{
}
public PrintTemplate(List data) : this()
{
cartData = data;
}
public void Default_Receipt(object sender, PrintPageEventArgs e)
