Same occurs using lp as client.

@dimonic ippserver is not a CUPS server and won't work directly with the "lp" command... ippserver printers should (depending on the printer attributes you supply) work with CUPS' IPP Everywhere support where the local cupsd will handle queuing, transforms, and sending the jobs to ippserver.
