It turns out this changes based on the media type.

 Glossy: 00 01 00
 Luster: 00 01 01
 Matte:  00 01 32

I currently have this specified in the model.xml's preInitRemoteSequence 
but that obviously won't do. 

I've been trying to add it as a parameter from within a <paper> definition:

   <parameter type="raw" name="escp2_preinit_remote_sequence">LB\003\000\000\001\001</parameter>

But it seems pd->preinit_remote_sequence is set in setup_basic(), far 
before the paper definition is parsed. I added a hack in 
adjust_density_and_ink_type() to explicitly check for that parameter:

  if (pv && stp_check_raw_parameter(pv, "escp2_preinit_remote_sequence", STP_PARAMETER_ACTIVE))
    pd->preinit_remote_sequence = escp2_preinit_remote_sequence(pv);

but that's a pretty ugly hack IMO. It perhaps makes more sense to add a 
generic LB command send into escp2_set_remote_sequence() and create a 
parameter to configure it.  But what should I call it?
