A processing apparatus for a print unit configured to print an image by using a printing material includes a processor configured to determine a value related to a remaining amount of the printing material in the print unit, output printing material information based on the determined value related to the remaining amount, and determine whether a replenishment printing material is ordered. The processor is configured to determine an order time to order the replenishment printing material by using the value related to the remaining amount of the printing material, and output the printing material information at a shorter interval before the replenishment printing material is ordered than after the replenishment printing material is ordered.
