Using Xerox FreeFlow® Print Server IPS Manager
appropriate interactions with the host take place, rather than simply terminating the job.
Because standard IPDS cancel processing differs from Xerox FreeFlow® Print Server cancel processing for other PDLs, there are a number of special cases that can occur, including:
•Handling a cancel attempt that is unable to complete
•Canceling a job that has completed decomposition
•Canceling a job that has not yet started decomposition
•Canceling a job when printer faults are active
•Requesting to cancel a job more than once
Xerox FreeFlow® Print Server presents an information dialog when IPDS cancel is requested. This dialog provides a Reset button. If standard IPDS cancel is taking too long, or is unable to complete for some reason, the user can click on the Reset button, causing all remaining IPDS jobs to terminate, and forcing IPDS communication with the host to be restarted. This button should only be used as a last resort, since if the job has not completed normally, the host will attempt to retransmit it, unless the user has first deactivated the job at the host.
IPDS cancel for Xerox FreeFlow® Print Server can only be performed for a job that is currently being decomposed. If cancel is requested for a job that has already been decomposed, the Print Server will display a fault message, stating that it is too late to cancel the job. In order to provide a way to clear a job that cannot continue, the fault dialog will provide a Reset button, as described above.
If the user attempts to cancel an IPDS job before a single page has committed to print, a fault message stating that cancel has been scheduled will be displayed. As in the too late to cancel scenario, the fault dialog provides a Reset button that can be used if necessary to force termination of IPDS jobs. If the Reset button is not applied, standard IPDS cancel processing will be performed once the Print Server is able to report to the host that a page has been committed for printing.
When printer faults are detected, the print server reports to the host that intervention is required. This causes the host to stop sending print data. Because standard IPDS cancel depends on printing the remaining committed pages, plus trailer pages, it cannot be performed when printer faults exist. When the print server detects an attempt to cancel a job when there are printer faults, it displays an additional fault message, informing the user of this situation. If the user clears the printer faults, cancel processing will complete. Alternatively, if the user clicks on the Reset button on the cancel faulted job dialog, all remaining IPDS jobs are forced to terminate, as described above.
If the user attempts to cancel a job more than once, a cancel dialog with a Reset button is provided as described above, allowing the user a means to clear the job from the system.
