Hi Bill, I have the same problem, so rest assured your not alone. I fixed mine. I'd like to share with you my fix and perhaps you might get back online.
This happened in error but it worked none the less, I reset my printing system via system prefs (this wipes your computer of all printers, regardless if they work or not! tread carefully)
No I had no printers installed, no loss right? It wasn't working on my Canon i5235iR network laser.
I then went to add a new printer, selected IP as the method, in the top address I put, the dns addy of my printer, in my case its 192.168.0.xx, then it searched and offered me a generic printer driver, I then chose to select the driver and in the search I put in my printer name and found the Mavericks driver , selected it and I was back online on the mavericks driver, all good.
Hope this helps.
