OK.  I'll try using the socket backend. . .

I'm confused about what the IPP backend was doing if it wasn't streaming.  Was it just copying so slowly that the printer decided (it's set to "intelligently" decide whether to wait for the entire file to be transferred before it starts) to print before receiving the 6 GB PJL/HPGL2 temporary file, which was able to be printed before it filled up a 4.8 GB hard drive?  The printer would take tens of seconds to print a single line for this test--it usually spits out an ~4'x8' poster in a few minutes, but it took hours for this print to finish using the IPP backend on CUPS.

Anyway, thanks for the information!

Well, I tried socket:, and I get a "network host 'hp-5000' is busy; will retry in 30 seconds." message from lpstat -p. . .  I guess we're stuck with the IPP backend for now. . .
