Pixma IP8720 suddenly not detected

[JoeZy]

When I first set up this printer - it would not connect wirelessly - fine - I set it up using USB - worked fine.

The next day - suddenly the printer could not be detected.  Spent a lot of time trouble shooting but eventually deleted  the driver and ran the set up again from the CD  -- everything went back to normal.

That happened twice since and although a hassle, repeated the set up and all good.

Today - it happened again (after months of working fine) -  I had finished printing about 30 13x19s with no problem.  About an hour later - the printer could not be detected.

I repeated removing the driver and device but this time running the set up again did not work (USB)

I've rebooted my computer and ran the set up 5 times - but then it gets stuck at "Turn on the Printer" -- nothing I've done can get it to detect the printer - even tried the wireless again to see if that would work --  nope --

any help is appreciated

The computer is still on windows 7 but it has been working great for months  -- it suddenly stopped working and will not reinstall -- can't detect the printer.  No software has been added between when it was working and when it stopped being detected.  I had also had turned off the firewall and virus protection - no change in behavior.
