1. An image forming apparatus comprising:
an interface configured to communicate with a network;
a main body memory configured to store therein:
an upper limit information indicating an upper limit of a printable page number that the image forming apparatus is allowed to print in a state where the image forming apparatus is in an off-line state where the interface is incapable of connecting with the network; and
a printed page number information indicating a printed page number printed by the image forming apparatus in the off-line state; and
a controller configured to:
in a state where the interface is in the off-line state, perform printing to print one or more sheets according to a print job;
when one sheet is printed, increment the printed page number information by one in a case where the one sheet is printed on one side printing, and increment the printed page number information by two in a case where the one sheet is printed on double-sided printing; and
after the printed page number information is incremented, determine whether the printed page number information is greater than or equal to the upper limit page number,
wherein, when the upper limit page number is reached with one additional page, the determining whether the printed page number information is greater than or equal to the upper limit page number is performed only after printing on one additional sheet is completed, regardless of whether one side printing or double-sided printing is performed on the one additional sheet.
