Introduction
I went looking for a class to do printing from a DataGridView, and none of them did all that I was looking for. I needed to print all pages, some pages, or the current selection; and I needed to not have objects, controls, or code from the printer object sprinkled through the rest of my code - i.e., it needed to be completely self-contained. Nothing I found met all those requirements, so I ended up writing my own.

DGVPrinter's various settings provide good control of all aspects of printing on the page. You can set the Title and Subtitles, add a footer, and control whether the page number prints in the header or footer. DGVPrinter supports Right-to-Left printing for non-Western languages and includes a drawing override for situations where a cell or column has onPaint overridden in the source DataGridView control. While the default styles for the printed DataGridView are taken from the source DataGridView control, DGVPrinter also provides many attributes that allow you to control the styling of almost every aspect of the printout.

History
Version 1.0 - Initial publication
Version 1.1 - Added footer handling, and allows the page number to print in the header or footer, and if it should print on the same line as the header or footer
Version 1.2 - Finally (I believe!), fixed the string/column alignment problems. Also prints cell background colors properly, respecting the alternating rows style
Version 1.3 - Added support for printing columns that contain images
Version 1.4 - Added support for printing directly to a provided Graphics object
Version 2.0 - Added support for printing images on the page
Version 3.0 - Breaking changes! Please read!

At the end of the method it does this. "but.Location = new Point (x, y);".
The problem is that by pressing the directional arrow, it changes the location of the button and does not continue with the focus on the button it focuses on another button.

public class AnnoyingButton : Button {

  protected override bool IsInputKey(Keys keyData) {
    return keyData == Keys.Up || keyData == Keys.Down ||
           keyData == Keys.Left || keyData == Keys.Right;
  }

  protected override void OnKeyDown(KeyEventArgs args) {
    Point newLocation = Location;

    switch (args.KeyCode) {
      case Keys.Right:
        newLocation.Offset(1, 0);
        Location = newLocation;
        break;
      case Keys.Left:
        newLocation.Offset(-1, 0);
        Location = newLocation;
        break;
      case Keys.Down:
        newLocation.Offset(0, 1);
        Location = newLocation;
        break;
      case Keys.Up:
        newLocation.Offset(0, -1);
        Location = newLocation;
        break;
      default:
        base.OnKeyDown(args);
    }
  }
}

You attached the key handler to the button. You should (probably) attach it at the form level
