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...
