How'd you go with this?
I'm having the same issues trying to get CP215W to work on Ubuntu 13.10 and have tried suggestions working from the linked thread above and others. Have tried Phaser 6000B drivers, a whole slew of generic drivers, etc. Have tried in USB/LAN/WLAN too.
The best I seem to get is that the print job is immediately cancelled by the printer or a PDL 016 720 error at the printer.
Currently suffering with printing via a Windows VM...
