Printing system

A printing method comprising:

• one or more steps in which print job data containing a plurality of objects is sent from one or more host apparatuses to one or more printers;
• one or more steps in which printing of the plurality of objects is carried out at one or more printers based on the print job data from host apparatus or apparatuses;
• one or more steps in which the print job data is stored;
• one or more steps in which operations carried out by the printer or printers in connection with printing of the plurality of objects are monitored and job status information is created for each one of the objects;
• one or more steps in which the created job status information is stored;
• one or more steps in which, in the event of occurrence of one or more printing errors during printing of the plurality of objects at the printer or printers, determination is made as to whether after occurrence of the printing error or errors the printer or printers has or have recovered from one or more printing error states to one or more states permitting printing;
• and
• one or more steps in which, in the event that it is determined that the printer or printers has or have recovered to the state or states permitting printing, one or more objects is or are selected from among the plurality of objects based on the stored print job data and the stored job status information, and printing of the selected object or objects is resumed.

A host apparatus sending print job data containing a plurality of objects to one or more printers and causing printing to be carried out, the host apparatus comprising:

• one or more first storage means for storing the print job data;
• one or more second storage means for storing job status information for each one of the objects, the job status information being created based on operations carried out by the printer or printers in connection with printing of the plurality of objects;
• one or more determining means for, in the event of occurrence of one or more printing errors during printing of the plurality of objects at the printer or printers, determining whether after occurrence of the printing error or errors the printer or printers has or have recovered from one or more printing error states to one or more states permitting printing;
• and
• one or more resumption instruction means for, in the event that it is determined that the printer or printers has or have recovered to the state or states permitting printing, controlling the printer or printers so as to cause resumption of printing of one or more objects selected from among the plurality of objects based on the print job data and the job status information, this having been permitted as a result of sending of the print job data stored at the first storage means and the job status information stored at the second storage means to the printer or printers.

A printer receiving print job data containing a plurality of objects from one or more host apparatuses and carrying out printing thereof, the printer comprising:

• one or more job status monitoring means for creating job status information for each one of the objects by monitoring operations carried out by the printer or printers in connection with printing of the plurality of objects, and for sending the created job status information to the host apparatus or apparatuses;
• one or more determining means for, in the event of occurrence of one or more printing errors during printing of the plurality of objects, determining whether after occurrence of the printing error or errors the printer or printers has or have recovered from one or more printing error states to one or more states permitting printing;
• and
• one or more print resuming means for, in the event that it is determined that the printer or printers has or have recovered to the state or states permitting printing, receiving the print job data and the job status information from the host apparatus or apparatuses, selecting one or more objects from among the plurality of objects based on the print job data and the job status information, and resuming printing of the selected object or objects.

A computer program for causing one or more computers to execute a method in which print job data containing a plurality of objects is sent to one or more printers and printing is caused to be carried out, the method comprising:

• one or more steps in which the print job data is stored;
• one or more steps in which job status information for each one of the objects is stored, the job status information being created based on operations carried out by the printer or printers in connection with printing of the plurality of objects;
• one or more steps in which, in the event of occurrence of one or more printing errors during printing of the plurality of objects at the printer or printers, determination is made as to whether after occurrence of the printing error or errors the printer or printers has or have recovered from one or more printing error states to one or more states permitting printing;
• and
• one or more steps in which, in the event that it is determined that the printer or printers has or have recovered to the state or states permitting printing, the printer or printers is or are controlled so as to cause resumption of printing of one or more objects selected from among the plurality of objects based on the print job data and the job status information, this having been permitted as a result of sending of the stored print job data and the stored job status information to the printer or printers.
