Panasonic DP 1820 as network printer using hpnp

[Shibin_2]

Hi,

I have configured some of the Panasonic DP network printer using hpnp. So far everything is working fine. But only one printer, Panasonic DP 1820, is not printing from the unix system.

Ping response is available. But the test printing is still waiting on the queue. Anybody can help me?

Here is some information, which may be helpful.

Hi

1)lpshut
#lpsched -v

Wait a while and look for extra messages in /var/spool/lp/log

Then
#lpshut
#lpsched

2)Try
#disable V312

Turn printer off - Turn printer on

#enable V312

The same I tried... Waiting for the end user reply to turn off the printer and on.

Since HPPI software is proprietary to HP, it is very unusual for any non-HP printer to work at all. A few big Canon printers understand hpnpf protocol (aka, JetDirect) and apparently, some models of Panasonic printers. You can see the failure mode by using hpnpf in trace mode. Bypass the spooler like this:

hpnpf -x 12.34.56.78 -l /tmp/hpnpf.log -N /etc/profile

The logfile will show what happened.

Hi Bill,

Using that option, I received the following on log file.

13:56:48 hpnpf[12716]

This printer does not understand HP's JetDirect protocol. You can verify this with the hpnpadmon command:

hpnpadmin -v 10.240.15.203

You'll have to delete the rpinter and add it back as a remote printer. You'll need to specify the remote printer's name which is hardcoded in the LAN card. You'll have to ask Panasonic about this name.

Earlier it was configured as remote printer. The same problem, it was not working. Later changed to network printer. There was one more printer had the same problem, when configured as remote printer. But, when I changed to network printer, the other one started functioning. I guess, it must be printer side problem. Let me confirm with end user.

I have rectified the issue.. with the same options..
