C# printing problem

[babaidebnath]

Hello all,
I am presently having a problem with printing in C#.
The problem is my customer provided me a pre printed paper and I
need to print value into some specific positions. But problem is C# for its
generic autofit to page nature dont let me doing this. Every time it is
decreasing whole page's size and also altering my value position into some
specific ratio. Can anyone tell me how can I come over that problem.
This is my code

 
//I AM USING PrintDocument COMPONENT
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
              //panelPrintData IS A PANEL CONTAING MY PRINTING PICTUREBOX,TEXTBOX,COMBO AND OTHERS NEED TO PRINT
              printDoc(panelPrintData, e);
        }
 
 
 public void printDoc(Panel p,PrintPageEventArgs e)
        {
            try
            {
                foreach (object obj in p.Controls)
                {
                    if (obj is TextBox)
                    {
                        TextBox txt = (TextBox)obj;
                        e.Graphics.DrawString(txt.Text, new Font("Arial", 10, FontStyle.Regular), Brushes.Black, txt.Left , txt.Top );
 
                    }
                    if (obj is Utility.LSInterfaces.IImagePrintable)
                    {
                        Utility.LSInterfaces.IImagePrintable img = (Utility.LSInterfaces.IImagePrintable)obj;
                        e.Graphics.DrawImage(img.Picture, img.Left , img.Top , img.Width, img.Height);
 
                    }
                    if (obj is LogiSoftUserControl.ResizableComponent.ResizablePictureBox)
                    {
                        LogiSoftUserControl.ResizableComponent.ResizablePictureBox img = (LogiSoftUserControl.ResizableComponent.ResizablePictureBox)obj;
                        e.Graphics.DrawImage(img.Picture, img.Left , img.Top , img.Width, img.Height);
 
                    }
                    if (obj is PictureBox)
                    {
                        PictureBox img = (PictureBox)obj;
                        e.Graphics.DrawImage(img.Image, img.Left , img.Top , img.Width, img.Height);
 
                    }
                }
            }
 
            catch (ArgumentNullException)
            { }
 
 
        }
 
 
//THIS IS BUTTON FOR PRINT
private void btnPrint_Click(object sender, EventArgs e)
        {
            DialogResult r = printDialog1.ShowDialog();
            if (r == DialogResult.OK)
                printDocument1.Print();
        }

Quick thoughts
A) Turn off auto size
B) Pre-format your document to the printable area of the printer so no scaling is required

A) Turn off auto size of what ?
B) If you can provide me . Some code of printable area (on my problem) will be helpful.....

Thanks

Having never used the PrintDocument component I had to look it up at MSDN
http://msdn.microsoft.com/en-us/libr...nt(VS.80).aspx

I took their sample and put it in a new project with nothing more than a file browser and a [Print] button.

Setting the e.Graphics.PageScale to 100 seemed to work for me.
I found this property by doing nothing more than typing e.Graphics. then looking at what IntelliSense showed me as available.

I've tested this on SnagIt printer (print to image), PrimoPDF (Print to PDF) and my Samsung CLP-510

namespace FormPrinting
{
    public partial class Form1 : Form
    {
        private Font printFont;
        private StreamReader streamToPrint;
 
        public Form1()
        {
            InitializeComponent();
        }
 
        private void btnPrint_Click(object sender, EventArgs e)
        {
            try
            {
                streamToPrint = new StreamReader
                   (browseFile1.Text);
                try
                {
                    printFont = new Font("Arial", 13);
                    PrintDocument pd = new PrintDocument();
                    pd.PrintPage += new PrintPageEventHandler
                       (this.pd_PrintPage);
                    pd.Print();
                }
                finally
                {
                    streamToPrint.Close();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
 
        }
 
 
        // The PrintPage event is raised for each page to be printed.
        private void pd_PrintPage(object sender, PrintPageEventArgs ev)
        {
 
            ev.Graphics.PageScale = 100;// Print at 100% or 1:1 ratio 
            //ev.PageSettings.PrinterSettings.
            ev.Graphics.DrawImageUnscaled(System.Drawing.Image.FromFile(browseFile1.Text),0,0);
            ev.HasMorePages = false;
            return; // Below here nothing runs. It is direct from the MSDN sample
 
            float linesPerPage = 0;
            float yPos = 0;
            int count = 0;
            float leftMargin = ev.MarginBounds.Left;
            float topMargin = ev.MarginBounds.Top;
            string line = null;
 
            // Calculate the number of lines per page.
            linesPerPage = ev.MarginBounds.Height /
               printFont.GetHeight(ev.Graphics);
 
            // Print each line of the file.
            while (count < linesPerPage &&
               ((line = streamToPrint.ReadLine()) != null))
            {
                yPos = topMargin + (count *
                   printFont.GetHeight(ev.Graphics));
                ev.Graphics.DrawString(line, printFont, Brushes.Black,
                   leftMargin, yPos, new StringFormat());
                count++;
            }
 
            // If more lines exist, print another page.
            if (line != null)
                ev.HasMorePages = true;
            else
                ev.HasMorePages = false;
        }
    }
}

I do have concerns that your placement calculations are off though.

e.Graphics.DrawString(txt.Text, new Font("Arial", 10, FontStyle.Regular), Brushes.Black, txt.Left , txt.Top );

So you take the text of a text box,and paint it onto a panel at the location of your textbox.

I don't see how this takes into account the resolution of the printer.
The textbox location is in pixels from the upper-left corner of the form.
Coming down 100 pixel and right 200 pixels is meaningless without knowing the resolution of the printer.

If the printer is 100dpi then down 100 pixels is down 1 inch.
If the printer is 300dpi then down 100 pixels is down 1/3 inch

Maybe the issue you are running into is the AutoScale of the printing, but rather your drawing on the panel is actually scaled down.
