As this printer natively supports PostScript (the spec says "HP PostScript 3 
emulation", buth that is perfectly OK), reconfigure the printer using the 
PostScript PPD (I'd prefer the HP supplied PPD over the foomatic generated 
one available at openprinting.org). Then the processing of the print job and 
submitting to the printer will occur in parallel.
