PIXMA TR4720 shows as "not connected" after 20 minutes

[apasq]

My TR4720 is connected and I can print, but after I don't use the computer for 20 minutes or so, the printer shows as not connected.  If I click on it, it goes green again, but I don't want to do this every time I print.  Is there a sleep function that I don't know about?  Thanks
