Can anyone save me some time on this one:

My Redhat 9 finds my local lp0 printer ok at boot time, and I've told kudzu not to complain if the printer isn't there at boot time (i.e. it's off), and all works fine. However, if I turn the printer on *after* I've booted up, jobs sent to the print queue don't make it to the printer.

This isn't a surprise to me, but how to I 'manually' tell Redhat that the printer is back?

Any replies appreciated,
Paul

Apologies, just realised the title of this post should have read 'if it was *off* at boot time'. My fault it nobody replies now...

You can try a couple of things :

a) Starting Kudzu - the hardware detection tool - as root, after startup :

"su -"
<your root password>
"service kudzu start"

b) Try to use CUPS - the Common Unix Printer Service :

Go to "http://localhost:631/printers" with Mozilla or Konquerer and click 'Start printer' on your selected printer.

Good luck.

Thanks for your reply.

I'd already tried 1. but it made my mouse go absolutely bonkers, and I had to kill X to recover!

So I tried 2, but there was nothing running on port 631.

I'll have to do a bit of reading I think!

You can check the port status with the command : "netstat -n -l -t".

It will probably look something like this :

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:901 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN

You can start cups with the following command :

"/etc/rc.d/init.d/cups start"

(..... or : "service cups start")

Then, look at your port status again :

"netstat -n -l -t"

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:901 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN

Then try to open "http://127.0.0.1:631/" from your web-browser.
