You can cancel a print job from the computer if transferring print jobs is not completed.
Double-click the printer icon on the Windows task tray.
A window appears, showing all print jobs currently queued for printing. Check the current status of the job you want to cancel.
Select the name of the job you want to cancel.
On the [Document] menu, click [Cancel].
Press the [Printer] key on the machine's control panel.
If the machine is shared by multiple computers, be careful not to accidentally cancel someone else's print jobs.
If the machine is connected to the computer using a parallel cable, sent print jobs may be canceled if [Reset All Jobs] is pressed while “Waiting for print data...” is on the control panel. After the interval set in [I/O Timeout] in Printer Features has passed, the next print job can be sent. A print job sent from a different client computer will not be canceled in this case.
Under Windows XP/Vista, or Windows Server 2003/2003 R2, click [Cancel] on the [Document] menu.
Under Windows 2000, you can also open the print job queue window by double-clicking the machine icon in the [Printers] machine window (the [Printers and Faxes] window under Windows XP and Windows Server 2003/2003 R2).
You cannot stop printing data that has already been processed. For this reason, printing may continue for a few pages after you press [Job Reset].
A print job containing a large volume of data may take considerable time to stop.
