More than likely it it C++, I recently wnet throught this exercise myself. There are OSS notes that explain label priniting depending on the printer and the label content (barcode or Text. Label printing is handled different in SAPscript than other printing. Without knowing the printer type as defined in SAP (device type, codepage, character set, etc), it is hard to tell what code this is. The numbers in a row define the type of code, the horizontal and vertical axis print start points. Additionally the SAPscript will contain the label’s content. If this is all that’s there it looks like it’s a template that you will have to add your content.
Hope this helps
