A print control apparatus includes a completion condition obtaining unit and a management unit. The completion condition obtaining unit obtains, when executing a print job for printing one or more pages satisfying a predetermined condition, a completion condition of the print job. The management unit manages the print job as uncompleted until the obtained completion condition is satisfied even when a recording material on which the one or more pages are printed is ejected.
