Printing system, method for controlling a printing system, image forming apparatus, controller of print system, and storage medium

A printing system capable of receiving a plurality of types of print jobs including a first type of print job that requires authentication processing prior to printing and a second type of print job that does not require authentication processing prior to printing, the printing system comprising:

• a job determining unit configured to determine whether a target job is the first type of print job that requires the authentication processing necessary in order to start printing of the target job or is the second type of print job that does not require the authentication processing;
• a resource determining unit configured to determine whether a quantity of a resource required to complete printing of the target job exists in the printing system;
• and
• a controller configured to cause the printing system to execute the authentication processing necessary to start printing of the target job,
• wherein, when the job determining unit determines the target job is the first type of print job, the controller causes the printing system to start the printing of the target job after the printing system executes the authentication processing necessary to start printing of the target job, if the resource determining unit determines that the quantity of the resource required to complete the target job exists in the printing system, and when the job determining unit determines the target job is the second type of print job, the controller causes the printing system to start the printing of the target job without determination by the resource determining unit.
