After a fresh installation of Ubuntu 14.04 I'm no longer able to print using the Ricoh Aficio MP C3001 printer that is accessible via samba on the network. Job completes normally but nothing gets printed.
It requires user authentification and an additional user code. The user code was configured using lpoptions -p printername -o UserCode=xxx which correctly changes ~/.cups/lpoptions with the user code. I also tried changing the ppd file with the custom user code instead of the predefined 100x values but this did not change the problem that I'm no longer able to print.
The printer gets detected and even seems to respond to a print job (it wakes up, but instead of printing, shuts down again). Printer works fine with the same settings using Windows and also previously worked with Ubuntu 13.10 and the same configuration.
Here is a (small) part of the cups error_log.

Troubleshooting guide did not help and printing a document does not give me any error messages.
