A barcode label is a special symbology to represent human readable information such as a material number or batch number
in machine readable format.
There are different symbologies for different applications and different industries. Luckily, you need not worry to much about that as the logistics supply chain has mostly standardized on 3 of 9 and 128 barcode symbologies - which all barcode readers support and which SAP support natively in it's printing protocols.
You can print barcodes from SAP by modifying an existing output form.
Behind every output form is a print program that collects all the data and then pass it to the form. The form contains the layout as well as the font, line and paragraph formats. These forms are designed using SAPScript (a very easy but frustratingly simplistic form format language) or SmartForms that is more of a graphical form design tool.
Barcodes are nothing more than a font definition and is part of the style sheet associated with a particular SAPScript form. The most important aspect is to place a parameter in the line of the form that points to the data element that you want to represent as barcode on the form, i.e. material number. Next you need to set the font for that parameter value to one of the supported barcode symbologies.
The next part of the equation can be a bit tricky as you will need to get a printer to print that barcode font. Regular laser printers does not normally print barcode fonts, only specialized industrial printers that is specifically designed to support that protocol and that uses specialized label media and heat transfer (resin) ribbon to create the sharp image required for barcodes.
Not to fear though, there are two ways to get around this:
- You can have your IT department do some research -
most laser printers can accept a font cartridge/dimm chip (similar to computer memory), called a BarDIMM that will allow a laser printer to support the printing of barcodes.
- Secondly, you can buy software that you can upload in your SAP print Server that will convert the barcode symbology as an image that will print on a regular laser printer. I found that this option results in less sharper barcodes. This option is really if you need to convert a large quantity of printers (>10) to support barcodes.
- Thirdly, you can buy a third party software like Barcode.dll and install on your frontend PC connected to the laser printer.

To Create a Bar code prefix:
1) Go to T-code - SPAD -> Full Administration -> Click on Device Type -> Double click the device for which you wish to create the print control -> Click on Print Control tab ->Click on change mode -> Click the plus sign to add a row or prefix say SBP99 (Prefix must start with SBP) -> save you changes , it will ask for request -> create request and save
2) Now when you go to SE73 if you enter SBP00 for you device it will add the newly created Prefix
Create a character format C1.Assign a barcode to the character format.Check the check box for the barcode.
The place where you are using the field value use like this
<C1> &itab-field& </C1>.
You will get the field value in the form of barcode.
Which barcode printer are you using ? Can you download this file and see.

It will give an idea about barcode commands.

Detailed information about SAP Barcodes
A barcode solution consists of the following:
- a barcode printer
- a barcode reader
- a mobile data collection application/program

______________________________________
To create barcode go to transaction se73 Then System Bar codes.
There are some barcodes already present.
If they solve your purpose,use them otherwise create new ones.
The main characteristics of barcodes are
1) Min. Char
2)Max Char
3)Width
4)Height
Now in your sapscript create a character format.
There you can see an option to select barcode.
From there select the appropriate type.
Now use this character format for the field you want to display the barcode.
