Bar-code prefix. The bar-code prefix places a reference in the table "Print controls for device type" in the spool administration. Print controls contain control commands for printers. The key to this table comprises the printer type and this prefix. The control sequence contained in print control is sent to the printer the actual bar-code data is sent. The prefix name should begin with SBP.
Example: If a printer type 'ZEXAMPLE' requires the control sequence 'BARC 8;' before the seven-character bar code 'ZEAN8' in order to print it: 1. the control sequence 'BARC 8;' must be maintained in table of print controls under the key 'ZEXAMPLE' 'SBP99', and 2. the bar-code prefix 'SBP99' must be entered for the printer type 'ZEXAMPLE' and the bar code 'ZEAN8' in the SAPscript font maintenance for printer bar codes.
