There are three ways to open a printer:
Click the Open [+] button to the left of the printer icon.
Select a printer, then choose Open from the Selected menu or from the printer's pop-up menu (displayed by pressing Shift+F10 or mouse button 3).
Double-click the printer icon.
Your job will not appear in the Print Manager or Printer Jobs window if there are no jobs waiting to be printed when you send your job to the printer.
