ABSTRACT:
In a printer system in which a plurality of virtual printers can be set, virtual printer names are properly used to select ordinary printing and security printing whose contents should be kept confidential. When print data whose contents should be kept confidential is printed, a virtual printer name for security printing, e.g., “sp2351”, is set upon directing printing. A printer identifies the virtual printer name for security printing by a part “sp”, and temporarily stores the contents to be printed in a memory. Subsequently, when the user inputs “2351” directly to the printer, printing is done.
