Failure to Print Multiple Copiee with Raw Option

How can we send PJL when doing a RAW job?  Do we need to create a queue with no PPD?  We still want to print a a job that isn't PDF through the PostScript drivers (and all the other controls gained from the PPD).  But we need the already formatted PDF to go direct to the plotter.

Ok, that makes sense.

LPD doesn't work.  I tried that too.  The data is sent multiple times.  I can't tell from the LPD data if it says how many copies, but if it does, the plotter wasn't honoring it.

IPP I was going to try next.  But, er, it isn't available on these particular plotters.  I was surprised since IPP is available on almost all our other new HP printers.
