Adding Your Own Bar Code Definitions

If you want to:

Add a new bar code

Use a predefined bar code on a printer other than those listed in Predefined Bar Codes

you must define the bar code in the SAP spool system and in SAPscript. Specifically, you must define the following:

The bar code in SAPscript, if it is not one of the standard, predefined R/3 bar codes. This is the system bar code definition.

The names of the print controls for turning bar code printing on and off. This is the printer bar code definition.

The printer escape sequences with which bar codes are turned on and off. These are the values for the print controls for turning a bar code on and off.

To define a bar code and activate bar code printing, do the following:

Define the Bar Codes in SAP script, if not already defined.

Copy the device type definition of the printer with which you are working. You can skip this step if you are adding a new type of printer to the SAP System.

Use the new device type in all of the printer definitions that you set up for printing with bar codes.

Example

You want to print bar codes on a Hewlett-Packard LaserJet 4 printer. This printer is predefined by SAP with device type HPLJ4. However, the standard printer definition does not include support for printing bar codes.

You need to create a copy of the device type, such as ZHPLJ4.

You need to add the print controls for turning off bar code printing to printer type ZHPLJ4, not to the standard HPLJ4 definition. You also need to use ZHPLJ4 as the device type in all of the Hewlett-Packard LaserJet 4 printers you define for printing bar codes in the SAP System.

Define the printer bar codes for the system bar codes you intend to use.

Enter the escape sequences (printer commands) for bar code printing in the print controls you have defined.

Choose Tools ® CCMS ® Spool ® Spool administration and then Full administration. Choose the DeviceTypes tab page, enter the name of the device type and confirm your entry.

Choose This graphic is explained in the accompanying text Print controls and enter the required printer commands to start and stop bar code printing. For information about which commands to enter, see the documentation provided with your bar code printing system.

Example: For SBP25 (from step 2), you would enter the escape sequence that switches the printer into bar code mode. For SBS25, you would enter the sequence that switches off bar code mode.

Note

See Adapting Bar Code Print Controls before you define your bar code print controls. The R/3 printer drivers handle the marking of bar code data differently, and this affects the escape sequences you must enter in your print controls.
