Download PCL (SFP) soft font to pcl6 interpreter?

There's probably a simple answer to this (and the answer is probably 
"No"), but I hope it's OK to ask anyway:

Using pcl6 to generate a PDF file, is there any way to download a PCL 
soft font to the interpreter together with the actual PCL print job so 
that the interpreter will use the soft font in the same way a physical 
printer would use a downloaded font? I understand that the font would 
need to be downloaded before each job, that it wouldn't be persistent.

I do know that I can *embed* a font in the PCL stream of a print job (I 
use that technique when printing from WordPerfect for DOS to pcl6), but 
I wonder if it's possible to achieve the same thing without embedding 
the font. I suppose I'm asking if there's already a command-line switch 
that would look something like

-download fontname.sfp

Thanks for any help, though my guess is that the answer will simply be, 
"Sorry, can't be done."
