ABSTRACT:
The present invention ascertains delimiting boundaries of print jobs quickly and accurately in a printing apparatus. The printing apparatus determines the type of PDL that describes print data received from a host computer. If a session is completed, 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. If none of the above apply, the printing apparatus stores the acquired print data in a receive buffer. If the data 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.
