and click Settings to open the Settings window. Next, click Printers to open the graphical

Printers tool and note that printer1 is displayed.

4. In the Printers tool, click Show Jobs and note that your recently submitted print job is

shown. Why arent the two other print jobs in the printer1 queue shown? Click Close

when finished.

5. In the Printers tool, click Print Test Page to submit a test page print job. Next, click

Show Jobs and note that two jobs are now displayed. Highlight your Test page job,
