Abstract:
1. A communication method for allowing a printing apparatus connected to a wireless LAN adapter having a wireless LAN communication unit and a memory, to perform wireless LAN communication via the wireless LAN adapter, said communication method comprising: a registration step of causing an external computer apparatus to register Service Set ID and printer ID of a target printer to use the wireless LAN adapter, into the memory of the wireless LAN adapter, in a case that the external computer apparatus is connected to the wireless LAN adapter, wherein the Service Set ID defines wireless LAN communication of the target printer via the wireless LAN adapter; a first reading step of causing the printing apparatus to read the printer ID from the memory of the wireless LAN adapter, in a case that the wireless LAN adapter in which the printer ID has been registered in said registration step is connected to the printing apparatus; a comparison step of comparing the printer ID read in said first reading step with printer ID of the printing apparatus preset in the printing apparatus; a notification step of notifying a user of an error, in a case that the printer ID of the printing apparatus does not match with the printer ID read in said first reading step, wherein the Service Set ID is not read from the memory of the wireless LAN adapter; a second reading step of causing the printing apparatus to read the Service Set ID from the memory of the wireless LAN adapter from which the printer ID is read in said first reading step, in a case that the printer ID of the printing apparatus matches with the printer ID read in said first reading step; a setting step of causing the printing apparatus to set the Service Set ID read in said second reading step in the wireless LAN communication unit of the wireless LAN adapter from which the Service Set ID is read in said second reading step; and a communication step of causing the wireless LAN communication unit of the wireless LAN adapter in which the Service Set ID is set in said setting step, to perform the wireless LAN communication, using the Service Set ID set in said setting step.
