Invoice Printing

Hi all,

My names are Andrew from Kenya. I work at a millk products plant called Sammer Agriculture. Currently we use SAP. At the Invoice department we print invoices fro various customers using SAP. The invoices are forwarded to the Epson dot matrix printer by Using an ETR machine as the default printer in SAP.

We have invoices that come out with the Grid lines (Table form). We would like to print without the grid lines , only words but no tables.

Please can anyone show how i change the printing option in SAP?
