I don't know but I will observe.

It only seems to happen after the printer has just been turned on, or after
it has been on but idle for a while. I cannot recall it happening in the
middle of any job.

The Linux box that uses the printer has been up for months. But the lp
drivers are modules; perhaps that has something do do with it? I tried to
rmmod lp and rmmod segfaulted. It refuses to unload parport_pc (device or
resource busy). Here is the output of lsmod:

Disturbing.

No other hardware, driver, or daemon uses /dev/lp0.
