determining whether a device in which the first identification information is set is present on a network to which the information processing apparatus is connected, in a case where the print queue in which the first identification information is set is registered in the print control software; and changing identification information of the print queue registered in the print control software from the first identification information to second identification information different from the first identification information, in a case where a device in which the first identification information is set is determined to be present on the network. ### Claim 2 (depends on 1) The control method according to claim 1, wherein a virtual printer in which the second identification information is set is registered as a virtual printer to communicate with operating system (OS) standard print software and associated with the print queue, in a case where a device in which the first identification information is set is determined to be present on the network, and wherein the identification information of the print queue registered in the print control software is changed from the first identification information to the second identification information, in a case where the virtual printer in which the second identification information is set is registered. ### Claim 3 (depends on 1) The control method according to claim 1, wherein a virtual printer, in which identification information formed by adding a number to an end of the first identification information is set as the second identification information, is registered in accordance with a discovery protocol, in a case where a device in which the first identification information is set is determined to be present on the network. ### Claim 4 (depends on 1) The control method according to claim 1, wherein an input item that receives a change of the identification information of the print queue registered in the print control software is displayed in a case where a device in which the first identification information is set is determined to be present on the network, and wherein a virtual printer in which the second identification information is set is registered as a virtual printer to communicate with OS standard print software and associated with the print queue, in a case where the identification information of the print queue registered in the print control software is changed from the first identification information to the second identification information by a user input to the input item. ### Claim 5 (depends on 1) The control method according to claim 1, further comprising executing processing of registering, in the OS standard print software, a print queue of the virtual printer in which the second identification information is set, in a case where a device in which the second identification information is set is determined to be absent on the network. ### Claim 6 (depends on 5) The control method according to claim 5, further comprising deleting a print queue in which the second identification information is set and which is registered in the OS standard print software, if a device in which the second identification information is set is determined to be present on the network in a case where the print control software is activated. ### Claim 7 (depends on 1) The control method according to claim 1, wherein, in a case where a printing apparatus that communicates with the information processing apparatus does not support print data in a standard format, print data in the standard format generated by the OS standard print software is transmitted to the virtual printer to be converted by the print control software into print data in a format interpretable by the printing apparatus. ### Claim 8 An information processing apparatus comprising: a first registration unit configured to register, in print control software, a print queue in which first identification information is set; a determination unit configured to determine whether a device in which the first identification information is set is present on a network to which the information processing apparatus is connected, in a case where the print queue in which the first identification information is set is registered in the print control software; and a changing unit configured to change identification information of the print queue registered in the print control software from the first identification information to second identification information different from the first identification information, in a case where a device in which the first identification information is set is determined to be present on the network. ### Claim 9 (depends on 8) The information processing apparatus according to claim 8, wherein a virtual printer in which the second identification information is set is registered as a virtual printer to communicate with OS standard print software and associated with the print queue, in a case where a device in which the first identification information is set is determined to be present on the network, and wherein the identification information of the print queue registered in the print control software is changed from the first identification information to the second identification information, in a case where the virtual printer in which the second identification information is set is registered. ### Claim 10 (depends on 8) The information processing apparatus according to claim 8, wherein a virtual printer, in which identification information formed by adding a number to an end of the first identification information is set as the second identification information, is registered in accordance with a discovery protocol, in a case where a device in which the first identification information is set is determined to be present on the network. ### Claim 11 (depends on 8) The information processing apparatus according to claim 8, wherein an input item that receives a change of the identification information of the print queue registered in the print control software is displayed in a case where a device in which the first identification information is set is determined to be present on the network, and wherein a virtual printer in which the second identification information is set is registered as a virtual printer to communicate with OS standard print software and associated with the print queue, in a case where the identification information of the print queue registered in the print control software is changed from the first identification information to the second identification information by a user input to the input item. ### Claim 12 (depends on 8) The information processing apparatus according to claim 8, further comprising an execution unit configured to execute processing of registering a print queue of the virtual printer in which the second identification information is set in the OS standard print software, in a case where a device in which the second identification information is set is determined to be absent on the network. ### Claim 13 (depends on 12) The information processing apparatus according to claim 12, further comprising a deletion unit configured to delete a print queue in which the second identification information is set and which is registered in the OS standard print software, in a case where a device in which the second identification information is set is determined to be present on the network, in a case where the print control software is activated. ### Claim 14 (depends on 8) The information processing apparatus according to claim 8, wherein, in a case where a printing apparatus that communicates with the information processing apparatus does not support print data in a standard format, print data in the standard format generated by the OS standard print software is transmitted to the virtual printer to be converted by the print control software into print data in a format interpretable by the printing apparatus.
