A user equipment issues a job for a plurality of documents to a printing system by one operation. The user equipment assigns attributes to the job, the attributes including the specification of collation/uncollation, the designation of processing start instruction wait, the designation of exclusive processing, and the designation of password input wait. The printing system effects printing of the plurality of documents corresponding to attributes of the documents under control of a job scheduling device. The job scheduling device carries out the pausing of documents included in the job, the modification of attributes, addressing of document receiving failures, and search of a document whose format is to be converted, thereby making it possible to efficiently print the plurality of documents.
