Hi

I just setup a CUPS printer on my slackware router machine. Accessed it
using localhost:631/admin and was able to print to it (was unable to browse
the printers to print a test page - but since lp -d hpoj (hpoj - name of
the queue) does the job, I am not worried about it, though I am curious
about this.).

My firewall script reads (relevant portions) :

IPPPORT=631
LAN_IP_RANGE="192.168.1.0/24"
LO_IP="127.0.0.1"

$IPTABLES -I INPUT -p tcp -s $LAN_IP_RANGE --dport $IPPPORT -j ACCEPT
$IPTABLES -I INPUT -p tcp -s $LO_IP --dport $IPPPORT -j ACCEPT


The funny thing was that port 631 (ipp) was not listed in /etc/services
and /etc/protocols. Had to hand edit them.

Now, the LAN above is a wireless network to which only one Debian powered
laptop is connected :

I edited the CUPS printer setup :

Device URI: http://192.168.1.1:631/ipp/lp0 (lp0 is the name of the parallel
port to which the printer is connected)

(192.168.1.1 is the IP address of the Slackware router with firewall).

Now when I try to print a test page from the laptop, I get :

"Unable to get printer status (client-error-forbidden)!"

When I tried to use the KDE printer tool to add the queue, it complained
that it could not find the queue on the server !

I like the idea behind CUPS, but the lack of documentation pertaining to my
network setup and continued inability to setup CUPS correctly is
frustrating. It used to be so much easier with LPD.

Any ideas ? If I am able to sort out this nonsense, I promise to document
my experience so that it eases the experience of others.

Thanks.

Further, I have the latest foomatic stuff installed, but HP OfficeJet K80xi
drivers are not available on the Debian machine (they are available on the
Slack router/print server).
