Might help if you gave information about what environment you are using. Could mean Crystal Reports, winforms, wpf.

If you are using C# to print directly, then you should be using a PrintDocument[^] object to do the print.

If you look at the PrintPage event, it includes the printable area as the PrintPageEventArgs.MarginBounds, and you have the size of your image, so centring it is just a case of setting the top left hand corner of the print position to the Width of the print area minus the Width of the image, divided by two for the X, and the Height of the print area minus the Height of the image, divided by two for the Y.

Feed that into the Graphics.DrawImage method, and it will be centred.

Thank you for your response. I tried what you suggested, my only problem now is that the image size is in pixels and while the print area is in inches. How do you convert from pixels to inches?

Check the PageUnit property - you should be able to change it to pixels.

Thanks. Its nice to have another alternative using PageUnit property but I already used someone elses suggestion on another post as the one below.

Image newImage = Image.FromFile("c:\\Documents\\pic.gif");

newImage.HorizontalResolution and newImage.VerticalResolution gives pixels/inch.
