I'm building a POS system on the AIR platform using Flash Builder. I'm trying to find a way to kick open the cash drawer that is hooked up to the receipt printer. Is there a way to set the font for the receipt printer (EPSON TM-T20) to the "control" font mentioned in the printer's documentation and send only the "a" character through in 1pt size? This seems like it would be the simplest approach. Does anyone know otherwise how to kick open the cash drawer if this method isn't possible, by sending raw characters to the printer or how to build a wrapper to talk to the driver directly?
