If you're looking to improve the productivity and lower the operating costs of your business, B4600 Series Digital Monochrome printers are made for you.

Just now, I was able to restore function, I can not explain the why, but I can tell you exactly what I did: I too had this issue on an C831, could not for the life of me get anything to work, removed and reinstalled drivers, reset my printer settings as per a few articles I saw, restarted my mac a few times etc.B4600 Series printers from OKI Printing Solutions are built for efficiency and speed, with expandability to meet your future needs. Turn the printer off with via the power button, not unplugging. Remove/delete the printer from your list of devices. Shut down your Mac, wait at least 30 seconds (I was working so it stayed off for a few minutes) then restart. Then I added the printer again, the same as I had done previously, no new tricks, my Mac detected my Oki and I clicked through the steps to reinstall. I can't be certain but I did select 'generic postscript printer' as opposed to using software for the drivers, (I don't remember doing this step previously and cant be sure what the default setting is, but that was my selection). As of now this seems to be working, I have read that this may need to be repeated eventually due to some corruption but that is beyond my technical expertise. Hope this works for you and in any case I hope Oki provides some updated drivers for us all! I don't usually update right away but I was so happy with the update on my phone I went ahead and updated my Mac as well.
