Printing system including server device capable of communicating with printers and client device

A printing system comprising:

• a first printer;
• a second printer;
• a server device configured to communicate with the first printer and the second printer;
• and
• a client device configured to communicate with the server device and comprising a client user interface,
• wherein the client device is configured to perform:
• (a) in a state where first authentication using first authentication information is successful, transmitting a print job based on an image to be printed to the server device, the print job being associated with a computer name, the first authentication information being received via the client user interface in advance, the first authentication information including user identification information, the first authentication being performed according to a first authentication method, the computer name being assigned to the client device, the computer name including the user identification information,
• wherein the server device is configured to perform:
• (b) in response to receiving the print job transmitted from the client device in (a), storing the print job in association with the user identification information, the user identification information being specified by the computer name associated with the print job,
• wherein the first printer comprises:
• a first user interface;
• and a first memory, the first printer being configured to perform:
• (c) receiving the first authentication information via the first user interface;
• (d) determining whether the first authentication using the first authentication information received in (c) is successful;
• (e) accessing, in response to determining in (d) that the first authentication is successful, the server device using first account information stored in the first memory, the first account information being used for accessing the server device with a permission to receive the print job;
• (f) receiving, from the server device accessed in (e), the print job stored in association with the user identification information, the user identification information being included in the first authentication information received in (c);
• and
• (g) printing the image based on the print job received in (f), and
• wherein the second printer comprises:
• a second user interface;
• and a second memory, the second printer being configured to perform:
• (h) receiving second authentication information via the second user interface, the second authentication information including the user identification information;
• (i) determining whether second authentication using the second authentication information received in (h) is successful, the second authentication being performed according to a second authentication method, the second authentication method being different from the first authentication method;
• (j) accessing, in response to determining in (i) that the second authentication is successful, the server device using second account information stored in the second memory, the second account information being used for accessing the server device with the permission to receive the print job;
• (k) receiving, from the server device accessed in (j), the print job stored in association with the user identification information, the user identification information being included in the second authentication information received in (h);
• and
• (l) printing the image based on the print job received in (k).
