Definitions

  • the present invention relates to a printing technique for executing print processing on the basis of a print job and, more particularly, to a printing technique of a print job that requires authentication processing.
  • a trial print (trial copy) function which trial-prints some pages prior to main print processing and starts print processing after it is confirmed if the user wants to start, cancel, change, or the like the main print processing is known (see Japanese Patent Laid-Open No. 2003-208298).
  • the printing operation of a job to be processed by this function is paused when the user confirms the trial print result or changes the job after confirmation.
  • the two functions i.e., the trial print and secure print functions are independent functions, and have no relevance to each other.
  • a job (secure job) which requires authentication to output, and a job (non-secure job) which does not require any authentication to output have a feature in that although they require different control processes before the beginning of execution, their control processes have no difference after their print processes start in practice. For this reason, upon executing the trial print processing of a secure job, when the owner of that secure job leaves from an image forming apparatus main body for the purpose of replenishing paper sheets for the main print processing, toner, or the like after the job is interrupted, a third party may manipulate the secure job which has undergone the trial print processing and waits for post-processing. Hence, the main print operation of the secure job may be executed, and the document security may not be protected.
  • the present invention has been made in consideration of the aforementioned problems, and has as its object to provide a technique for maintaining the security of a document to be printed even after execution of trial print processing, when trial print processing is to be executed based on a secure job. It is another object of the present invention to prevent a problem such as poor usability or the like, which is posed to maintain the security after the trial print processing of a secure job upon execution of the trial print processing of a job other than the secure job such as a non-secure job, and to simultaneously realize an effect of maintaining security even after the trial print processing of a secure job and an effect of improving usability upon execution of the trial print processing of a non-secure job.
  • a job processing method of the present invention comprises the following arrangement.
  • a job processing method in a printing system includes a printing device can accept a plurality of types of print job including a print job of a first type and a print job of a second type, the method comprising the steps of:
