When I installed slack I installed both cup and lprng I couldn't print. I then found out there was a bug that made cups stop working, so I reinstalled cups and removed lprng.... many times, in different combinations. However, I always get:

lpr: error - scheduler not responding!

when I try to print. I set up the printer in cups using the web-based setup, and can print test pages.

cupsd starts when I boot, but it seems there is a problem with the scheduler, whatever that is..

What's a solution so I can print?

It's been a few days without any replies.... Without being able to print, my linux setup is severely limited. Does anyone have any ideas? Is there crucial information that I forgot?

Try 'lpr-cups' instead of 'lpr'.

I had problems with lpd and cups, too. The scripts rc.cups and rc.lprng in /etc/rc.d were not executable. Since I made them executable my printer works.

lpr-cups gives the same error.

/etc/rc.d/rc.cups and /etc/rc.d/rc.lprng are both executable.

Any other ideas?

... 2 years later:

For the archives, this error started happening to me. I googled without finding a fix.
I tried enabling the local cups port, with the Mandrake 10 'drakfirewall', and that
seemd to fix it, oddly. The print server is on the same LAN, with no firewall.

This doesnt make sense - the firewall should only affect connections from outside. The local cups server should be reachable via 127.0.0.1:631, which lpr-cups does.

Re-blocking the cups port didn't bring the problem back, but it came again later.
Opening the port seemed to fix it again. beats me.

I believe the original problem was with Slackware's packages - installing both CUPS and LPRNG at the same time would screw it up. And if you reinstalled them it didn't fix itself - kinda messy. So now I only install CUPS :-P

Don't know about Mandrake, but that was the story for Slackware.

To print from a printer connected through LAN I used the following command
lpr -E -H 192.168.1.254:445 -#1 a.txt

But its giving the error message:
lpr: Error - scheduler not responding!

Help me please.....

What distribution are you running? The more information you give, the easier it will be to help you.

What do you mean by 'distribution'? Give some example....

e.g.

Slackware 12.0
Redhat 8.1
Ubuntu 7.10
...

Redhat Enterprise Linux AS4

Well, your problem isn't Slackware related at least

But more information that you can give helps us help you, otherwise we are forced to make uninformed guesses.

Are you sure the printer you are connecting to is turned on and shared properly? Is the ip address the right one?

Yes, the IP address of the printer is correct. And the printer is also turned on and properly shared because I'm able to print from windows using the same printer.

Hello!
I find solution at forums.whirlpool.net.au/forum-replies-archive.cfm/425285.html:

"...after having a quick look at the cups source code I found out that the problem was that the environment variable CUPS_SERVER wasn't set. So running "export CUPS_SERVER=localhost" before using lpr at the command line now makes it work fine."
