When creating barcode for low resolution printers, it's always best to set X Dimension to a value that aligns with the size of the printer dot.  This can be done easily by setting UnitOfMeasure to a value with your printer's dots-per-inch resolution. For example:

BarCodeWiz1.UnitOfMeasure = Unit_DotAt203dpi
BarCodeWiz1.XDimension = 4.0 // Set the X Dimension to thickness equal to 4 dots

For displaying barcodes on screen at 96 dots-per-inch:

BarCodeWiz1.UnitOfMeasure = Unit_DotAt96dpi
BarCodeWiz1.XDimension = 2.0 // Set the X Dimension to 2 pixel
BarCodeWiz1.BarHeight = 96.0 // Set Bar Height to 96 pixels (1 inch)
BarCodeWiz1.OutlineWidth = 1.0 // Set width of outline to 1 pixel
