Since you get a bitmap out of ZXing you can use standard C# techniques to draw text. See this answer for more info:

c# write text on bitmap

For posterity here's some shamelessly copied code:

Bitmap bmp = //from ZXing;

RectangleF rectf = new RectangleF(70, 90, 90, 50);

Graphics g = Graphics.FromImage(bmp);

g.SmoothingMode = SmoothingMode.AntiAlias;
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.PixelOffsetMode = PixelOffsetMode.HighQuality;
g.DrawString("yourText", new Font("Tahoma",8), Brushes.Black, rectf);

g.Flush();
