I am trying to set up a web based POS system and have got everything working apart from printing directly to a barcode / label printer.
When printing to the barode printer I need to send it a text stream of ascii characters with none printable control characters. Here's an example <STX> is the ascii stx character (HEX 0x02) <CR> is the ascii line termination character (HEX 0x0D)
Does anyone know how I could generate this stream and send it to the printer (or windows print spool)?
Thanks for any help.
