The problem I have is that when I see a preview or print a report in MS Access, the numbers below the code appear very very small.
In Access a report is designed in a lower resolution (pixels per inch) that it is using while printing. So it is required that you create the barcode control with a much bigger font size than you would normally use. Otherwise the text line under the barcode may be very very small in your print. So change the font size for the text line (font.size property of the control) to a much bigger size even if the barcode control may display a size error in design mode.
