Troubleshooting
Another possibility is that the Ipr program is not setuid root, setgid ,pooling. This can be
checked with
%
Is -Ig /usr/ucb/lpr
Jpr: printer: printer queue i. disabled
This means the queue was turned
01
with
%
Ipc disable printer
to prevent Ipr from putting files in the queue. This is normally done by the system
manager when a printer is going to be down tor a long time. The printer can be turned
back on by a super-user with Ipe.
LPQ
waiting ror printer to become ready (omine ?)
The printer device could not be opened by the daemon. This can happen tor a number
ot
reasons, the most common being that the printer is turned ol-line. This message can also
be generated if the printer is out of paper, the paper is jammed, etc. The actual reason is
dependent on the meaning
ot
error codes returned by system device driver. Not all printers
supply sufficient information to distinguish when a printer is off-line or having trouble (e.g.
a printer connected through a serial line). Another possible cause
ot
this message is some
other process, such as an output filter, has an exclusive open on the device. Your only
recourse here is to kill off the offending program(s) and restart the printer with Ipe.
printer is ready and printing
The Ipq program checks to see it a daemon process exists tor printer and prints the file
,tatu,. If the daemon is hung, a super user can use Ipe to abort the current daemon and
start a new one.
waiting ror ho,t to come up
This indicates there is a daemon trying to connect to the remote machine named lao,' in
order to send the files in the local queue. If the remote machine is up, Ipd on the remote
machine is probably dead or hung and should be restarted as mentioned tor Ipr.
sending to holt
The files should be in the process of being transterred to the remote lao,"
It not, the local
daemon should be aborted and started with Ipe .
. Warning: printer
is
down
The printer has been marked as being unavailable with Ipc.
Warning: no daemon present
The lpd process overseeing the spooling queue, as indicated in the "lock" file in that direc-
tory, does not exist. This normally occurs only when the daemon has unexpectedly died.
The error log file for the printer should be checked for a diagnostic trom the deceased pro-
cess. To restart an lpd, use
%
Ipc restart printer
lprm: printer: cannot restart printer daemon
This case is the same as when Ipr prints that the daemon cannot be started.
