Have you tried different printer drivers other than the one that's "recommended"?
I just found the problem. The firmware on the printer was from January 20, 2011. I went to HP's website and noticed a massive firmware update from December of 2014. I downloaded the .zip file, unzipped it to get the .rfu file needed to update. And then I did:
cat ljP4000fw_04.221.6.rfu > /dev/usb/lp0
This upgraded my printer to a December 30, 2014 firmware update, and now...printing works fine!
Sorry for the bother, everyone. As one person here told me, "if it's not a firmware issue, it's a CUPS configuration issue."
Yep...
