(1) Choose "S: Print Using SAP Protocol" if a print server with SAPlpd or SAPsprint is used to print barcodes.
(2) Choose "F: Printing on Frontend Computer" if SAPlpd and SAP GUI are used together to print barcodes, SAP GUI sends print job to SAPlpd, SAPlpd is started automatically and forwards the print data stream to the Windows print manager.
(3) Choose "G: Frontend Printing with Control Tech", only SAP GUI is involved in printing barcodes, SAPlpd is not used.
