lpd problem

Hello all,

Out of curiosity, has anyone else run into a problem like mine.....

...RH print server - when the lpd daemon starts up it spools 2 daemons - which halts freezes all printing. The workaround is to kill one of the daemons. Also, for the past week or so I have had to stop and restart the daemon almost every time I go to print.

Sounds like to me the daemon may be corrupt. Any ideas on how I can fix this problem?

Please Help - Lpd Problem

I am relatively a new Linux user and I am having a problem using lpd which is driving me crazy. The following describes my system and the exact problem I am having:

OS: Red Hat Linux 6.0
Kernel: 2.2.5-15 on an i686
Printers used: Okidata MicroLine 320

I have 4 network (connected using Cisco router) printers running and I print to these printers using the lpr command, for example I type "lpr -Pqueuename Filename". For the most part it works fine, but frequently (atleast once a day) for no apparent reason one printer or the other stops printing. And when I do a
#ps -aux |grep lpd command I see two lpd daemon's running

root 412 0.0 0.6 1120 404 ? S 11:30 0:00 lpd
root 417 0.0 1.1 1432 756 ? S 11:30 0:00 lpd
root 500 0.0 1522 392 pts/1 R 11:45 0:00 grep lpd

and when I goto the particular printer queue directory I see the c* file and the d* file. The only way I can make the printer work again is if I manually remove these cfA005A9zI525 and dfA005A9zI525 files and then restart the lpd daemon by typing:
/etc/rc.d/init.d/lpd restart
and then type
# lpc restart printerqueuename

and when I do all these steps, the printer starts working again.

A sample of my /etc/printcap file is as follows:

PRINTTOOL3## REMOTE epson 60x60 letter {} Epson9 Default {}
#PRINTTOOL3## REMOTE epson 60x60 letter {} Epson9 Default {}
#PRINTTOOL3## REMOTE epson 60x60 letter {} Epson9 Default {}
#PRINTTOOL3## REMOTE epson 60x60 letter {} Epson9 Default {}

I had set /etc/printcap file using the printtool feature. The printers we are using are the Okidata Microline 320 (9 pin printer). In the printtool application I could'nt find any Okidata hence I used the epson 9 pin filter.

The other problem I have is that whenever I print a big file, the printer prints few pages and then stops printing and I see that another child lpd daemon is created and then I have to do the whole above process again to make the printer work again.

Can anyone make me understand why all of sudden for no apparent reason one or the other printer stops working which seem to create child lpd daemon?

I have spent several hours online trying to understand the whole lpd process. The only conclusion I have come to so far is that the lpd is not a stable utility.

I would appreciate any help I could get.

Re: lpd problem

I am having the same exact behaviour -- lpd runs fine much of the time, but
will mysteriously freeze a queue for no obvious reason. I have to bring the
queues down using lpc (lpc down all), go into /var/spool/lpd and remove all
the dF* and cF* files, restart the queues (or sometimes even restart lpr
completely). Then the print queues will resume working.

Doing a "ps -ax|grep lpd" and "kill -9 XXXX" on the lpd (Worker - Remote) PID (doing an lpc status all will also show you the current PID for the print job) will some times get the q back to work with out having to remove all your jobs.

I am having the same problim with a mass amount of jobs halting LPD
Please E-mail if you know the answer!!!!
