The present invention prevents erroneous setting of paper size based on capability information transmitted from a virtual printer to an OS. A printer application (170) is configured to execute the following steps: a step (S120), a step (S205), and a step (S220) of acquiring tray information, paper state information, and tray paper setting information relating to a paper tray provided in a printer (200) and paper to be printed stored in the paper tray; a step (S140) and a step (S150) for generating an attribute suitable for the paper feeding environment of the printer (200) on the basis of the tray information, the paper state information, and the tray paper setting information; and a step (S160) for outputting the generated attribute to the CUPS (160).

The present invention enables a user to execute a unique print setting based on a virtual printer corresponding to a desired printing device without performing a process corresponding to the virtual printer. An initiator (106) causes a processor (110) of a terminal device (100) to execute: a step (S20) for outputting display data for causing a display unit (140) of the terminal device (100) to display a dialog box (DB1) capable of selecting a plurality of printers (200) corresponding to a plurality of printer applications (170); a step S400 in which a selection operation of one printer (200) among the plurality of printers (200) is accepted in the displayed dialog box (DB1); and a step S420 of performing a process for causing one printer application (170) corresponding to the one printer (200) accepted in the step S400 among the plurality of printer applications (170) to display, on a display unit (140) of the terminal device (100), a print setting screen of the one printer (200) for which the selection has been accepted.

To provide technology that enables effective use of virtual printers by linking the OS's standard printing function with support programs. [Solution] The auxiliary program 42 instructs the OS 21 to create a printer queue 22b for the virtual printer associated with the auxiliary program 42, and can identify, for example, an unsupported device 2 as a device corresponding to the virtual printer. Furthermore, when the virtual printer is selected and an instruction to display the detailed settings screen is given, and processing is requested from the general-purpose printing program 41, the auxiliary program 42 displays a detailed settings screen based on the capabilities of the identified unsupported device 2 to the user IF 13. When a print instruction is given with the virtual printer selected, and processing is requested from the general-purpose printing program 41, the auxiliary program 42 acquires image data indicating the image to be printed, and sends a print job containing print data based on the acquired image data to the identified unsupported device 2.
