Apparatus and method for changing printer driver, and printing system and method using it

Command buffer the present invention is to store, and the printer driver to change the print command device driver related to a configurable printer and method using the same system and the printer driver to change the device and method; Driver storing section that stores the plurality of the driver corresponding to the printer model; When the printer identification information is input from the driver storing section select driver for selecting a corresponding driver for the printer identification information portion; And by the driver performing a print command stored in the command buffer and by generating a predetermined data for printing, and when a given error occurs during instruction processing, and characterized in that it comprises a command processing section which outputs an error signal, the driver changes available printer system host that receives the printer identification information or the printer driver changes the request from a plurality of drivers for a printer, select the printer driver that corresponds to generate predetermined data for printing; And select the printer emulator corresponding to the selected printer driver on the host to process the predetermined data for the print produced by the host it characterized in that it comprises a printer for printing. According to the present invention, it allows the user to reliably print when a print job. It also provides a convenience to the user by changing the appropriate printer driver automatically without the user having to change the driver even when there is an error.
