US Patent 7170619 Information processing apparatus, printing system, and command generating method

A user sets a desired print function for a printer having a print function. In accordance with the set print function, whether a printer control command recognized by the printer is generated by an application for a host computer or a printer driver is determined. If an additional function of the printer driver, e.g., an N-page print function, a printing/bookbinding function, or the like is set, the printer driver generates a printer control command. If no additional function is set, the application generates a printer control command. The generated printer control command is output from the system spooler of the host computer to the printer.
