I can get Font.size and printFont.GetHeight(PrintPageEventArgs.Graphics), number of characters in string to print.
With the PrintDocument pd=new PrintDocument and printFont=new Font("Arial",10) I think it is possible to determine
the length in inches on the printed sheet.
I need this to make sure the string is within a area of the printedsheet, that is in fact I am printing labels on aA4sheet
of paper.
What information do I need and how to calculate the printed length of a string?   

Inside of your graphics object, there's a method available to you:

"System.Drawing.Graphics.MeasureString(string, System.Drawing.Font)"

Other overloads exist for this functionality.

Divide the height by pd.DefaultPageSettings.PrinterResolution.Y, which should get you the height in inches.

Yes, Graphics.MeasureString() will tell you how big the printed string will be.  However, for labels you are usually more interested in getting the string in the right place.  For that, use the Graphics.DrawString(string, Font, Brush, RectangleF, StringFormat) overload.  The StringFormat argument determines how the string is fitted inside the rectangle.
