1. A pull printing system, comprising: a printing device that executes a printing job; a pull printing server that spools the printing job that is executed as pull printing by the printing device; and an electronic device that transmits the printing job to the pull printing server; wherein: the electronic device comprises a control unit including a Central Processing Unit (CPU) and a storage device including a printer driver; the control unit executes the printer driver to function as a pull printing setting unit that executes settings for the pull printing, and a printing job transmission unit that transmits the printing job to the printing server; the pull printing setting unit displays a setting screen for the pull printing on a display of the electronic device; the setting screen includes: (i) a first setting to enable execution of the pull printing; (ii) a second setting to set identification information and authentication information of a first person providing a transmission instruction for the printing job to the pull printing server; and (iii) a third setting to set identification information of a delegate user as a second person providing an execution instruction for the pull printing, who is different from the first person providing the transmission instruction; when authentication based on the identification information and the authentication information of the first person providing the transmission instruction from the electronic device is successful, the printing job transmission unit includes both the identification information of the first person providing the transmission instruction and the identification information of the second person providing the execution instruction in the setting screen, in a Printer Job Language (PJL) for transmitting the printing job; when both the identification information of the first person providing the transmission instruction and the identification information of the second person are included in the PJL, the pull printing server spools the printing job received from the electronic device related with both the identification of the first person providing the transmission instruction and the identification information of the second person providing the execution instruction; when authentication based on the identification information and the authentication information of the second person providing the execution instruction received from the printing device is successful, the pull printing server transmits to the printing device a list of spooled printing jobs related with both (i) the identification of the first person who has set the second person as the delegate user in the setting screen, (ii) and the identification information of the second person; and the printing device displays the list of the spooled printing jobs received from the pull printing server, the spooled printing jobs related with the identification of the first person who has set the second person as the delegate user in the setting screen being displayed in the list with the identification of the first person as an authorized person.
