Claim Text:
1. A printing apparatus comprising: a processor coupled to a memory; a printing unit configured to perform printing processing; a setting unit configured to set a permitted port number based on user's designation; a determination unit configured to determine, in a case where the printing apparatus receives print data, whether a port number used when the print data is received corresponds to the permitted port number set by the setting unit; and a control unit configured to permit the printing unit to perform printing processing based on the print data in a case where the determination unit determines that the port number used when the print data is received corresponds to the permitted port number set by the setting unit, and to prohibit the printing unit to perform printing processing based on the print data in a case where the determination unit determines that the port number used when the print data is received does not correspond to the permitted port number set by the setting unit, wherein the printing apparatus is able to perform a direct wireless communication with an external apparatus, wherein, in a case where the printing apparatus receives print data via a wired LAN I/F, the control unit permits or prohibits the printing unit to perform printing processing based on the print data, according to a result of the determination by the determination unit, wherein, in a case where the printing apparatus receives print data from the external apparatus via the direct wireless communication, the control unit permits the printing unit to perform printing processing based on the print data regardless of a result of the determination by the determination unit, and wherein the setting unit, the determination unit, and the control unit are implemented by the processor.
