Printer won't print? Fresh Ink, No outstanding jobs? Hmmm...try this

I ran into this situation at a friend’s house. I had set a lengthy manual to print out when I had to leave the house for several hours.

The printer had run out of paper when I returned. I put more paper into it and it still wouldn’t work. 

I went to the Printer & Fax preference and cleared the printer jobs. But still no printing.

I had the sense to remember that OS X has a number of caches for various things. By rebooting the Mac and starting up again in SAFE mode by holding down the left SHIFT key, I cleared the caches. 

I then rebooted the Mac to put it back into normal mode so that I could print wirelessly. SAFE mode disables wireless communication.

Voila! The printer would now print. I finished the over 200 page job and my friend was very happy.
