SAP barcode printing to citizen CL-S621

Hi Friends,

I need to enable barcode printing from sap ecc system to Citizen CL-S621 printer.

I've given the device type as SAPWIN but the barcodes are not coming as expected.

Few of the barcodes are printing fine but always coming in small letters.

Could some one help me to find what exact setting do I need to maintain for barcode printing

to Citizen CL-S621

Thanks and Regards,

Nikhil
