Process hpnpf

[Elizangela_1]

Hi,

The queue for netowrk printers are buffering.
When this occur, the process hpnpf in the top command show 90% de CPU.

Every time I have to execute the cancel -e and the process die.

What is output of:

hpnpadmin -S

Have you tried restarting the scheduler?

Hi,

I restart scheduler, but continue the same.

When execute the comand, output is
lp9900: Unknown printer
: Error sending SNMP request.
*** Can't find the session!

But the printer exist

Thanks

[Geoff Wild]

ok - lp9900 - is it a jet direct printer? or is it remote? Can you resolve it with dns?

nslookup lp9900

Can you ping it?

How about:

lpstat lp9900

Rgds...Geoff

[Elizangela_1]

I can't ping it.

Output of nslookup command:

Using /etc/hosts on:

looking up FILES
Trying DNS
looking up FILES
*** No address information is available for "lp9900"

Output of lpstat in this moment show nothing, because always I need to cancel jobs, if not process hpnpf appear on top with 90% de cpu.

Geoff,

In the file /etc/lp/interface/printer name, the variable PERIPH have the ip 10.51.1.50, but cant't ping it.

[Geoff Wild]

The spooler relies on DNS - it has the be able to resolve the printers....

Do you know the ip address of the printer?

If yes, as a test - just add it to youe /etc/hosts file.

Hi,

I add in /etc/hosts, but jobs still in the queue. When I execute the lpstat - command this appear.

[Geoff Wild]

Yes, if you can't ping it, or connect to it with hpnpadmin, then you will not be able to print to it. Best thisng to do is to disable it:

disable lp9900

Then try to find out if the printer is powered off or if you have a network issue...


Rgds...Geoff

[Elizangela_1]

OK..

I did a test with another printer that can ping.

The job for this printer still in the queue but I can ping.

When I tried connect to hpnpadmin, output is

Control Panel : not specified
Line State : Offline

[Elizangela_1]

Hi,

It's very difficult!!!!!

I did a test with another printer that ping, but can't connect with hpnpadmin .

What's relation?

If ping the printer, necessary connect with

hpnpadmin?

Thanks

[Geoff Wild]

Line State : Offline

That means the printer is offline and will not accept print jobs. Someone has to put it online.

Another thing to check is to make sure you are using the latest jet direct software...

[Elizangela_1]

But after upgrade the jet direct sofware, I need to install all printers again?

[Geoff Wild]

You shouldn't have to re-install the printers...just in case, backup your spooler configuration:

Backup the spooler configuration:

/usr/sam/lbin/lpmgr -S -v -xsavedir=/var/sam/lp/

cd /var/sam
tar cvf lp.tar lp

If you have to restore:

cd /var/sam
tar xvf lp.tar
/usr/sam/lbin/lpmgr -R -xsavedir=/var/sam/lp/
