Re: Oracle Report using printer code

I've tried using the printer code from the epson manual and create a prt file, I can get the output to be set to bold or italic, however it is can get the barcode printed. May be using barcode true type font in Oracle Report is the better way, rather then using the manufacturer printer code....
