printing an image in a4,a3 sheet

Hi, you can print an image using the PrintDocument[^] class.

Just use the Graphics.DrawImage() method in the PrintDocument's PrintPage event:

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) 
{
   e.Graphics.DrawImage(m_image, 0, 0);
}

The above code assumes that your image is loaded in

Bitmap m_image;

member.

For setting the paper size you can use PrintDocument's DefaultPageSettings.PaperSize property.

I hope this helps! :)
Regards
