                double Height = Convert.ToDouble(p_height);
                double width = 0;
                double aspectRatio = 0;
                aspectRatio = (double)PictureBox1.Image.Width / (double)PictureBox1.Image.Height;
                width = Height * aspectRatio;
                    int wi = 0;
                    wi = Convert.ToInt32(width);
                    int hi = 0;

            e.Graphics.DrawImage(PictureBox1.Image,0, 0);
        }

Hi
hunar abubakir,
Could you show me your screen capture on your side? It could be better to help us understand your scenario more clearly.
Now based on your code, What I first think of in my mind is that I doubt the width is more than 827. So please try to debug your code to see whether the width size
is appropriate.
By the way, Are you sure the A4 size is (827, 1169)?
If your picture size is ok, another possibility is the setting of printer.  Using
Margins(0, 0, 0, 0) to set the border. But still will meet result in the edge getting cut off in the printer.
Some similar scenario like yours
Margin Bounds Wider & Taller In PrintDocument.Print() Than In PrintPreviewDialog.ShowDialog()
Here is a way to print Borderless on your printer, It is Inkjet Printer. My suggestion is you could ask your IT department for better help.
