1) Install the barcode font from the internet somewhere in your system and every system that will use your document

2) Type numbers into a cell that is formatted to display using the barcode font

3) Print away

That really depends on what kind of barcode you want to use. Many barcoding systems use complex algorithms to encode the data before outputting it for the barcode. Most also have start/stop codes that need to be incorporated into the barcode.
