If the printer has a parallel interface on lptx, maybe it's possible to
print and do sound at the same time by using lptcontrol to change the
printer from interrupt-driven to polled. I'm not sure at what point
during bootup one needs to do this, but presumably it's before sounds
play, and before anything is spooled. Drop a command into rc.local and
try it out. :-) (Changing to polled also solved my recent problem
printing to a Panasonic KX-P4400.)
A bug in my MUA causes news.announce.newusers font
to be sent to beneficiaries and senders of UCE/SPAM. @
