Communication apparatus, printing apparatus, printing system including said communication apparatus and printing apparatus, and method of controlling same

Abstract

In response to a search command issued from a communication terminal, a printing apparatus declares to the communication terminal that the printing apparatus possesses an analyzing function for analyzing information described in a structured language. The printing apparatus analyzes description data, which relates to a communication method described in a structured language transmitted from the communication terminal, and communicates with the communication terminal in accordance with the communication method.

1 . A printing system comprising a communication terminal for supplying print data to a printing apparatus, and a printing apparatus for receiving and printing the print data, wherein said communication terminal includes:
 a declaration unit, in a case where the communication terminal has an analyzing unit for analyzing information described in a structured language, configured to declare to the printing apparatus that the information is capable of being analyzed;   a transmission unit, in a case where the printing apparatus is capable of analyzing the information described in the structured language, configured to transmit description data, which relates to a communication method described in the structured language, to the printing apparatus; and   a communication control unit configured to communicate with the printing apparatus in accordance with the communication method described by the description data; and   the printing apparatus includes:   a unit, in a case where the printing apparatus has an analyzing unit for analyzing information described in structured language, configured to declare to the communication terminal that the information is capable of being analyzed;   an interpretation unit configured to interpret description data relating to a communication method described in the structured language transmitted from the communication terminal; and   a print communication control unit configured to communicate with the communication terminal in accordance with the communication method described by the description data.
