Sorry. I wish I knew how to replicate this problem, but I can't. (Un)fortunately, my CUPS installs are all rock-solid.

Some command I can give to see why the server hangs?

Code:

# ps | grep cups
 5830 root       0:00 /usr/sbin/cupsd -C /etc/cups/cupsd.conf
# /etc/init.d/cups status
cups: scheduler is running.
# /etc/init.d/cups restart
cups: restarted scheduler.
# cups-config --version
1.3.11


Sob... Sad

Try this:

Stop CUPS with the command: /etc/init.d/cups stop

Delete these folders, if they exist

/var/cups
/var/log/cups
/var/run/cups
/var/spool/cups
/var/cache/cups

Restart CUPS with: /etc/init.d/cups start

One thing:

since first reboot after my "waiting for localhost" problem, before X starts I can read this warning:

Code:
WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.


and here's /etc/modprobe.conf content:

Code:
options parport_pc io=0x378 irq=7 dma=3


Is it related?

That message has been around for a while. What Puppy version are you using?

Are you installing from the PET or from the official Samsung installer?

I removed your pet now, anyway I re-factored it leaving only the ppd of my printer, to save some space.

Anyway with no save file loaded the pet worked and the printer printed.

With my current savefile instead, no matter what I install or delete, I can't get any CUPS webpage but the home... Crying or Very sad

mikeb wrote me a PM about double checking possible changes in file / folders permissions.
I gave a look but did not find anomalies.

Then I looked at cups conf file adding ErrorLog file and setting LogLevel to debug.

Code:
D [12/Jan/2011:20:03:03 +2300] cupsdReadClient: 10 GET /admin?OP=add-printer HTTP/1.1
D [12/Jan/2011:20:03:03 +2300] cupsdAuthorize: No authentication data provided.

E [12/Jan/2011:20:03:03 +2300] PID 9232 (/usr/lib/cups/cgi-bin/admin.cgi) stopped with status 22!
D [12/Jan/2011:20:03:03 +2300] [CGI] /usr/lib/cups/cgi-bin/admin.cgi: Permission denied


The second last line reports the error, I checked binaries in /usr/lib/cups/cgi-bin/ but all have rwx,r-x,r-x permissions so I don't understand the Permission denied last message.

According to this error 22 is:

Code:
#define EINVAL          22      /* Invalid argument */


Any tip?

I think that adding as a default the cups error log (in /var/log/cups/ like Ubuntu) in all puppies could help a lot not experienced users.
