Cancelling a file but it still keeps printing can occur. USB, for example, is slow to cancel. Sometimes a file can take minutes to clear (delete) from a print queue. Even if the AccuRIP Print Queue Window, Epson Printer Drive Print Queue, Mac Print Queue are clear the Operating System can still be sending data to the printer. That process should stop, but if it is too slow then restart the computer and printer to end (stop) services immediately and start again.
If all print queues are clear and you restart your computer there should be print services sending data to the printer.
