The present invention, the object of which is to ascertain the delimiting boundaries of print jobs quickly and accurately in a printing apparatus, discloses printing control in which a printing apparatus determines the type of PDL that describes print data, which has been received from a host computer, from a portion at the beginning of the print data. The printing apparatus acquires print data from an interface with the host computer. If a session is completed, or data cannot be received within a fixed period of time, or if end of PDL defined by an end-of-job command is found, then the printing apparatus delimits a print job using the position at which the above event occurs as the end of the PDL. If none of the above apply, on the other hand, the printing apparatus stores the acquired print data in a receive buffer. If the data is data that immediately follows end of PDL, then the printing apparatus regards this data as the beginning of another print job, newly assigns a job identifier to this print job and stores the same in the receive buffer. The stored print data is managed in correlation with the job identifier thereof.
