I have a malibu printer on an IRIS 3130. The printer has been working
OK for some time, but now refuses to print. lpstat -t gives the
error message
disabled by scheduler: can't open /dev/ttyd3
As far as I can see, all the permissions are as they always were
and resetting them to their old values does not trigger the
scheduler. Stopping and starting the print queue has no effect.
Could this be a hardware problem? Or would I get a different
message from lpstat if it couldn't activate the printer? Any help
much appreciated.

Try something to hold the port open like: nuhup sleep 10000000 < /dev/ttyd3 & and then re-enable the printer. This is usually done in /etc/rc.local when the system is started, but something may have happened along the way..
