An information processing apparatus includes a printer driver configured to generate a print command compliant with a predetermined printing protocol based on print data obtained from a data generation application, one or more extension modules configured to generate a print command compliant with another printing protocol different from the predetermined printing protocol, a storage unit configured to store information associating the one or more extension modules to be used for generating the print command compliant with said another printing protocol with the printer driver, and an output unit configured to output the print command compliant with said another printing protocol, the print command being obtained through processing of the print data obtained by the printer driver, and the processing being performed by the one or more modules indicated by the information.

When a general-use printing program receives a print instruction to cause a printer to execute printing of an image, a supporting program receives a print parameter used for processing intermediate image data. When the print parameter includes a setting of image combining of combining a watermark with an image subjected to printing in accordance with the print instruction, the supporting program causes a PC to generate a watermark to be combined with the image subjected to printing.

A non-transitory computer-readable storage medium stores a support program for an information processing device connectable to a printer. In an operating system of the information processing device, a general-purpose printing program corresponding to the printer is embedded. The support program, when executed by a computer of the information processing device, causes the information processing device to perform: acquiring; requesting; and processing. The acquiring acquires, in response to a print instruction being issued from an editing application program, status information from the printer. The requesting requests a displaying application program to display a notification screen by transferring a parameter based on the status information to the displaying application program. In response to the print instruction being issued from the editing application program, the processing processes for transmitting print data based on the print instruction to the printer without waiting for the displaying application program to terminate displaying the notification screen.

A control method for an information processing apparatus that communicates with the information processing apparatus includes acquiring information on a first printing apparatus, displaying a first selection screen including a first display item regarding the first print apparatus on a display unit based on the acquired information on the first printing apparatus, and receiving, on the first selection screen, an instruction for registering the first printing apparatus onto the print control software. Based on the reception of the instruction for registering the first printing apparatus on the print control software, the first printing apparatus is registered onto the print control software and on OS-standard print software.

In a case where a registration state of a printing apparatus in operating system (OS) standard print software and a registration state of the printing apparatus in print conversion software do not match each other, an information processing apparatus performs a process for matching between a registration state of a print queue of the printing apparatus in the OS standard print software and the registration state of the printing apparatus in the print conversion software.

Provided is a controlling method of an information processing apparatus provided with an extension application program for extending a function of print data creation software to create print data, the controlling method including: displaying a print setting screen by using the extension application program; and performing control such that a prescribed print setting item being displayable by the extension application program based on predetermined information based on information obtained from a printing apparatus by the print data creation software is not displayed on the print setting screen to be displayed by the extension application program.

When a general-use printing program receives a print instruction to cause a printer to execute printing of an image, a supporting program obtains status information of the printer from the printer and determines, based on the status information, whether a display condition is satisfied. The display condition is a condition to display a message based on the status information. When it is determined that the display condition is satisfied, the supporting program display the massage on a UI of a PC.

A supporting program according to aspects of the present disclosures can be executed by a CPU of a PC and corresponds to a printer connected to the PC. When the PC receives a print instruction to cause the printer to perform printing through a general-use printing program implemented in the OS of the PC, in advance, the supporting program causes the PC to output a preceding operation command to cause the printer to perform a preceding operation before starting printing. The printer performs a preceding operation corresponding to the preceding operation command.

A control method of an information processing apparatus on which an expansion application configured to expand a function of print data generation software configured to generate print data runs, is provided. The control method comprises obtaining attribute data on a printing apparatus, the attribute data being output from the printing apparatus, obtaining data indicating a print function, and adding information related to a specific function based on attribute information included in the obtained attribute data if information indicating the specific function is not included in the obtained data indicating the print function. A setting screen including a setting item of the specific function is displayed based on the added information related to the specific function.

A control method implemented in an information processing apparatus by at least one processor that executes print control software, the control method includes registering, in a print control software, a print queue in which first identification information is set, determining whether a device in which the first identification information is set is present on a network to which an information processing apparatus is connected, in a case where the print queue in which the first identification information is set is registered in the print control software, and changing identification information of the print queue registered in the print control software from the first identification information to second identification information different from the first identification information, in a case where a device in which the first identification information is set is determined to be present on the network.
