Trouble Printing to Canon LBP6300dn

[Craig]

Hi Cups Members,

Issue:
Print jobs seem to dissapear from the cups print queue but never actually print (Canon LBP6300dn Network Printer).

* Using the cups logs, I cannot see a single error (even with debug on).
* Canon ccpd daemon is running fine, but doesn't seem to be writing any log files
* When I run the "/usr/local/bin/captstatusui" monitor tool, it sits there in "Ready Mode" and never seems to get the print job. It does appear to be working perfectly though, because it can clearly detect if I unplug the printer (either via USB or LAN).


Question:
1) How is the cups daemon meant to communicate with ccpd daemon? I assume it's meant to use the "PDATA_Port  59687" but googling shows other members using a ccp:/var/ccpd/fifo0 DeviceURI?

2) Any debug options to this Canon ccdp daemon?
