Information processing apparatus, method of controlling the same, information processing system and storage medium

A client computer that displays a status of a printer on a display of the client computer, the client computer comprising:

• at least one memory that stores (a) an operating system having a bidirectional communication module that is capable of communicating with the printer bidirectionally and is not allowed to be customized, (b) a status display application, and (c) a bidirectional communication application;
• and
• at least one processor that executes the operating system, the status display application, and the bidirectional communication application,
• wherein the at least one processor, by executing the status display application, obtains the status of the printer using the bidirectional communication application without using the bidirectional communication module of the operating system and displays the obtained status of the printer on the display.

An information processing apparatus having a language monitor being capable of performing a bidirectional communication with a printer, and for outputting print data to the printer using the language monitor, wherein the printer is able to perform print processing based on the print data, the image processing apparatus comprising:

• a status display application that displays a status of the printer;
• and
• a bidirectional communication application that communicates with the status display application and is able to perform the bidirectional communication with the printer,
• wherein the status display application transmits an acquisition request of the status of the printer to the bidirectional communication application, wherein the acquisition request includes information for identifying the printer,
• wherein the bidirectional communication application transmits the acquisition request to the printer identified by the information included in the acquisition request without using the language monitor and transmits information based on the status of the printer that is received from the printer without using the language monitor as a response to the acquisition request to the status display application, and
• wherein the status display application displays the status of the printer based on the information based on the status of the printer that is received from the printer without using the language monitor in accordance with having received the information based on the status of the printer from the bidirectional communication application, and the status display application is further operable to display a status of the print processing by the printer.
