Abstract
While a specific application is running, a printer driver enables printing other data that is not data from the specific application. A dedicated driver (printer driver) that runs on a POS terminal occupies a communication port when receipt data is supplied from a POS application. The dedicated driver also sends print data generated based on the receipt data through the communication port to a POS printer. After continuing for a previously set time, the dedicated driver releases the communication port.
