This eliminates the ethernet cable and the printer part of the issue.
The remaining component of the transport system is the backend filter.
Test it with

  lp -d XXX -o raw out.dat

This sends out.dat to the printer without going through the filtering
system. XXX is the queue name. You probably know what it is or it can
be obtained from below.

Also provide the outputs of

 lpstat -t

and

 lpinfo -v
