Photosmart premium c309a, mac (lion os) says it's not connected. after weeks of printing. why?

Question

Photosmart C309a series [E9584E].  Has worked well for around a year.  Recently upgraded Mac to Lion, and it still worked fine.  More recently the computer says the "the printer is offline"  or "not connected".  Have unplugged the printer, shut down the desktop and then plugged in the printer, waited and started up the desktop.  Did not work.  Not sure what to do next.  Any ideas?
Thank you.

Hi,
First, turn both the Mac and Printer Off.
Unplug the router for 30 seconds and then turn all the devices back On.
Now check for any change.
If there is no change, try resetting the Printing System and then add the device again.
*Be aware that resetting the printer system will remove any existing print queue and reset any customized driver settings.
Click the Apple menu, and then click System Preferences .
Select Print & Scan.
Right-click (or Ctrl + click) your product in the Printers list in the left panel, and then click Reset printing system .
Click OK to confirm the reset.
Type your user Name and Password .
Click OK . The printing system resets.
Enter System Preferences > Print And Scan.
click the Plus sign and add your printer, then check for any change.
