Sorry for the previous replies. Now that you have clarified your issue I can understand what you are experiencing. For the record, I have never had this symptom on any Mac and hence my confusion with what you were seeing.
Whenever I print, the printer queue for that printer appears in the Dock, and if I click on it before it quits I see a pane that provides the ability to Delete, Hold and Pause a print job for that print queue.
If you are not getting the same then I suggest you try resetting the printing system, which will require you to add the print queues again.
To reset the printing system, open Print & Fax and move your mouse over the Printers list. Then hold down the Control button and click your mouse. When reset printing system appears, let go of the Control button and click the reset text. This will remove all printer queues but not the associated driver files. So, if you unplug the i70 USB and reconnect, the printer should automatically appear back in the Printers list.
