Modprobe or insmod them (ppa and lp) but not both at the same time.

If you don't know, then it's unlikely to be, because you would have
had to compile it. But uname -r will tell you.

So the zip drive was switched on at the time (but no disk).

If you're using a stock kernel, I presume ppa and lp are modules,
and that you installed then in the installation program, ie, both
are therefore mentioned in /etc/modules.

You could remove their names and either insert them manually at
appropriate times, or rely on kerneld to do it for you when you
print or mount a zip disk.
