Bar Codes and SWIN (SAP Library - SAP Printing Guide (BC))

Bar Codes and SWIN

To print bar codes on any Windows printer, do the following:

Define the printer in the SAP spool system with device type SWIN.
Specify Access method S in the printer definition in the spool system.
Install a *.DLL file on your Windows PC.

SAP does not offer a bar code.DLL. You must obtain the.DLL from another source.

These *.DLLs convert bar codes to graphics. Any printer that can print graphics can therefore print the bar codes, and no font cartridge is required.

The bar code.DLL must meet the following requirements:

It must be compatible with your Windows printers and with the R/3 SAPlpd transfer program running on the Windows PC.

To be compatible with SAPlpd, the bar code.DLL must offer a programming interface that meets SAPlpd’s requirements. These interface requirements and known compatible products are documented in SAP Note 25344. You can view the interface requirements as of the time of this writing in Bar Code.DLL Compatibility With SAPlpd.

The.DLL must be named BARCODE.DLL.

The.DLL must be located in one of these directories:

The winnt directory
The directory in which SAPLPD.EXE resides.

Note SAPlpd does not use the PATH variable to find the BARCODE.DLL.
