- Find the printer you are looking for, right-click on it, and select "Open." Click on the "Printer" menu at the top left hand corner and hit "Cancel all documents."
On Mac:
- Open System Preferences and click on the Print and Fax icon.
- In the list of printers on the left, select the printer you want to clear.
