What I have done in the past (I no longer have a printer on my desktop,
just the Zip drive) is daisy chain the printer and Zip drive. Then use
"rmmod XXX; modprobe ppa" and "rmmod ppa; modprobe XXX" as appropriate,
where XXX is the appropriate parallel port printer driver. Can anyone tell
us what XXX is on recent systems?
Don't disable the printer with printtool or anything else; just don't send
anything to the printer while you are using the Jaz drive. I seem to
recall that doing so is non-fatal, but if you forget that you did you
might find yourself with multiple copies of the document after you
reinstall the printer driver. :-)
