> I got a little problem here and you might be able to help me.
>
> One of my applications runs under Linux Red Hat 6.2 and it's accessed by a
> few users using telnet (tera term). This Linux box has only one printer
> connected to the Paralel interface and it's the only printer that we have
> for the whole building to print reports out of this application on Linux. We
> also have several networked printers (using TCP/IP) in our building and I
> was wondering how I could better use these printers.

> What I need is something like this:
>
> If a user using IP 192.168.1.X tries to print, use printer 192.168.1.111
> If a user using IP 192.168.2.X tries to print, use printer 192.168.2.222
>
> It can be also like this:
>
> Group X, prints on printer X (IP 192.168.1.111)
> Group Y, prints on printer Y (IP 192.168.2.222)
>
> The application won't let me do this...
>
> Do you have any solution for this. I am sure there is a way to do it, I just
> don't know how...

> I hope you can help me. Thanks in advance,

You need to determine the queue to use based on the originating
host address.
.common:lp=/var/spool/lpd:
lp:tc=.common:chooser=/usr/lib/libexec/chooser:
:sv=lp1,lp2
lp1:tc=.common:[EMAIL PROTECTED]
lp2:tc=.common:[EMAIL PROTECTED]
Chooser:
Here is a simple test version you can use:
#!/bin/sh
echo CHOOSER $0 "$@" 1>&2
echo PRINTERS $PRINTERS 1>&2
sed -e 's/,.*//'
exit 0
The output looks like:
Printer: [EMAIL PROTECTED] (subservers t5, t6)
Queue: no printable jobs in queue
Server: no server active
Status: CHOOSER: CHOOSER /var/tmp/LPD/chooser [EMAIL PROTECTED] -CA
-D2004-03-11-16:38:48.596 -Hh110.private -J/tmp/hi -Lpapowell -Pt4 -Qt4 -aacct -b3
-d/var/tmp/LPD/t4 -hh110.private -j358 -kcfA358h110.private -l66 -npapowell -pt4
-rlocalhost -sstatus -t2004-03-11-16:39:20.062 -w80 -x0 -y0 acct at 16:39:20.069
Status: CHOOSER: PRINTERS t5,t6 at 16:39:20.069
Status: Filter_file: pgm '/var/tmp/LPD/chooser' exited with status 'JSUCC' at
16:39:20.072
Status: CHOOSER selected 't5' at 16:39:20.072
Status: moving '[EMAIL PROTECTED]' to subserver 't5' at 16:39:20.075
Status: [EMAIL PROTECTED]: job '[EMAIL PROTECTED]' printed at 16:39:20.143
Status: job '[EMAIL PROTECTED]' saved at 16:39:20.146
Status: transfer '[EMAIL PROTECTED]' to queue 't5' finished at 16:39:20.147
Status: starting subserver 't5' at 16:39:20.147
Status: waiting for server queue process to exit at 16:39:20.165
Status: no more jobs to process in load balance queue at 16:39:20.221
Now you have to modify the chooser code to use the -H value for selection:
#!/bin/sh
while [ "$1" ] ; do
case $1 in
-H* ) host=$1;;
esac;
done
host=`echo $host | sed s/-.//`;
case $host in
192.1.1.1 ) pr=lp1;;
* ) pr=lp2;;
esac
echo $pr
exit 0
You can even use:
.common:lp=/var/spool/lpd:
lp:tc=.common:chooser=/usr/lib/libexec/chooser:
#!/bin/sh
while [ "$1" ] ; do
case $1 in
-H* ) host=$1;;
esac;
done
host=`echo $host | sed s/-.//`;
case $host in
192.1.1.1 ) [EMAIL PROTECTED];;
192.1.1.2 ) [EMAIL PROTECTED];;
esac
echo $pr
exit 0
