I am a Linux user of a Oki C3300 Color Printer, which needs your driver.
I am using the networked version, so no access via USB.
In my opinion the best way to access this printer via Ethernet is to use
internal LPD spooler of the printer.
You can simply check this with nmap, the port 515 is open, or you can
enable it in the WEB frontend.
So in Cups the queue looks like this:
IP adress differs, if you are using dhcp or fixed IP.
C3300-DBE0A6 is the printer-name.
With this setting it is possible to print out in very few time.
