I was able to find a fix/workaround and regain LAN printing to the Canon
with the latest kernels.

I went into Printer Properties for the printer.  The Device URI looked like this:
    cnijbe2://Canon/?port=net&serial=F4-91-39-42-53-Z1  (Not my printer's real MAC address but you get the idea)
I changed it to 
   ipp://192.168.1.6 (where that is the LAN IP of the printer, permanently assigned in my router)

And it worked!

Title:
  Lost ability to print on LAN printer with 3.16.0-51 kernel

Status in linux-lts-utopic package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to new kernel, attempts to print resulted in no
  printer activity and no error messages.  Printer is Canon Maxify 2320
  using Canon Linux drivers and is attached via LAN.  Rebooted into -50
  kernel and printing worked normally again.

  Symptom is print job shows up in queue but is never sent to printer.

  Scanning function of printer works.
