I am using epson's OPOS with the help of Mark's oposdemo download. I have been able to get my receipts to print. I would like to add a barcode to the bottom of my receipt. The manual shows the following command to print a barcode:

oleOPOS.PrintBarcode(PTR_S_RECEIPT,"cBarcode#",PTR_BCS_UPCA,100,150,PTC_BC_CENTER,PTR_BC_TEXT_BELOW)

I cannot find anywhere in the manual where it states what values the PrintBarcode method wants for PTR_S_RECEIPT, PTR_BCS_UPCA, PTC_BC_CENTER and PTR_BC_TEXT_BELOW. 100 and 150 are height and width of the barcode.

Any help would be appreciated.

Thanks

Pat
