Generally, printers need extra hardware or software to print bar codes. Many printers cannot print bar codes at all. Be sure to check that this feature is available before you acquire a printer.
Some printers are able to generate check numbers from the bar code data. For other models, you must provide the check number in the data that you send to the printer. If your printer cannot generate check numbers, then check the documentation of your SAP applications to determine how to send the check number as part of the bar code data.
For more detailed information about bar code support in the SAP System, see SAP Note 5196 in the SAP Service Marketplace.
For information on the bar code .DLL (dynamic link library) for use in Microsoft Windows PCs, see Bar Codes and SWIN .
