Printer and non-transitory computer readable storage medium

A printer comprising:

• a print engine;
• and
• a communication interface,
• wherein the printer is configured to:
• receive a print job from an IPP client via the communication interface according to internet printing protocol (IPP);
• and
• cause the print engine to perform printing based on the received print job,
• wherein the printer is configured to respond with the capability information in response to receiving a specific command from the IPP client via the communication interface, the specific command being specified by IPP and requesting capability information indicating capabilities of the printer,
• wherein the specific command includes a parameter for designating a requested capability, the parameter for designating a requested capability including a plurality of types, the plurality of types including a specified parameter that is the parameter specified in the IPP and a unique parameter that is the parameter not specified in the IPP,
• wherein a first setting value and a second setting value are to be set for a specific print setting item specified in the IPP, the first setting vale being a print setting value corresponding to a capability specified in the IPP, the second setting value being a print setting value corresponding to a unique capability of the printer, and
• wherein after responding with the capability information that includes the second setting value corresponding to the unique capability of the printer in response to receiving the specific command including the unique parameter, the printer is configured to, in a case where the print job designating the second setting value included in the response capability information for the specific print setting item is received from the IPP client, cause the print engine to perform printing based on the received print job, according to the second setting value.

A non-transitory computer readable storage medium storing a support program executable by a computer of an information processing device, the support program cooperating with an IPP client program included in an operating system of the information processing device,

• the support program causing the computer to execute:
• a capability acquisition process of transmitting, to a printer, a specific command specified by an IPP that requests capability information indicating capabilities of the printer, and of acquiring the capability information received from the printer as a response,
• wherein the specific command includes a parameter for designating a requested capability, the parameter for designating a requested capability including a plurality of types, the plurality of types including a specified parameter that is the parameter specified in the IPP and a unique parameter that is the parameter not specified in the IPP, and
• wherein after receiving the specific command, the printer is configured to:
• in a case where the unique parameter is not included in the received specific command, respond with the capability information that includes, among the capabilities of the printer, a capability specified in the IPP and does not include a capability not specified in the IPP;
• and
• in a case where the unique parameter is included in the received specific command, respond with the capability information that includes, among the capabilities of the printer, a unique capability of the printer that is designated by the unique parameter and is not specified in the IPP,
• the support program causing the computer to further execute:
• a display process of causing a user interface of the information processing device to display a selection screen for selecting a print setting value for a specific print setting item specified in the IPP, the selection screen including an option corresponding to a print setting value based on a capability included in the capability information acquired from the printer, and in a case where the unique capability is included in the capability information acquired from the printer, the selection screen further including an option corresponding to a print setting value based on the unique capability included in the capability information;
• and
• a job transmission process of transmitting, to the printer, a print job designating the print setting value corresponding to the option selected on the selection screen.

• a communication interface,
• wherein the printer is configured to:
• receive a print job from an IPP client via the communication interface according to internet printing protocol (IPP);
• and
• cause the print engine to perform printing based on the received print job,
• wherein the printer is configured to respond with the capability information in response to receiving a specific command from the IPP client via the communication interface, the specified command being specified by IPP and requesting capability information indicating capabilities of the printer,
• wherein the specific command is associated with identification information for identifying the IPP client that is a request source, and
• wherein the printer is further configured to:
• in a case where the received specific command is associated with the identification information indicating a first type IPP client, respond with the capability information that includes, among the capabilities of the printer, a unique capability of the printer that is not specified in the IPP;
• and
• in a case where the received specific command is associated with the identification information indicating a second type IPP client, respond with the capability information that includes, among the capabilities of the printer, a capability specified in the IPP and does not include the unique capability not specified in the IPP.
