Hello UNIX-people!

I'm having some trouble with our network printers.

I have about 10 NEC laser printers connected to a Sun4 server running
4.0.3.  Every once in a while, one of the printers gets into a state where
it's "waiting for lock on /dev/ttyN" where N is the printer device.  No
combination of lpc commands seems to remedy this...I've had to physically
disconnect the printer from the serial port to get rid of this state.  I
have also tried things like sending an end-of-file character to the
printer.  What does this state really mean?  What is lpd really waiting
for?  Any suggestions to remedy this situation would be greatly
appreciated!
