Abstract:
1. A printer system comprising: a plurality of printers; a client terminal which specifies a target printer at which printing is to be performed, of said plurality of printers, wherein said client terminal does not include a printer driver; a server which sends printing data for performing printing to the target printer, through a communications network; and one router disposed at a server side at which said server is provided and another router disposed at a client terminal side at which said client terminal is provided, and wherein said server comprises said client terminal comprises said target printer executes printing in accordance the printing data which is supplied from said sending unit, wherein each of said client terminal and said another router monitors a transmission speed at which the printing data is transmitted from said communications network to said target printer, and sends, in a case where the transmission speed exceeds a predetermined threshold value, negotiation information representing that the transmission speed of data transmission from said communications network to said target printer exceeds the predetermined threshold value, to said one router, and said one router, upon reception of said negotiation information, lowers the transmission speed of data transmission from said server to said communications network, and thereby the transmission speed of data transmission from said server to said target printer via said communications network is adjusted to be equal or less than the predetermined threshold value.
