Changing IP-address on remote printer on HP-UX

[K. Munk Kristensen]

Hi!

I have to change the IP-address of remote printer on a HP-UX server. I have tried with SAM but it seems I have to "Remove..." and then "Add Remote Printer/Plotter..."!? Or can I just edit some file somewhere?

[Chris Wilshaw]

check the printer interface file in /etc/lp/interfaces

It should contain a line that starts

PERIPH=

This will either have the IP address for the printer, or the name if it's been set up in the hosts file or DNS.

[Robert-Jan Goossens]

Hi,

check the /etc/hosts file.

# grep ipadress /etc/hosts

Hope it helps.

Robert-Jan.

Hi!
IP Address? - So you mean Network printer.
Try to find script, related to this
printer in /etc/lp/interfaces and
edit the line:

PERIPH =

Rgrds.

[K. Munk Kristensen]

Hey..

Thanks for a very quick answer - but sorry
I don't have the /etc/lp/interfaces file.

When looking at the printer with SAM I can see
the IP address in the "Location" column:
printer1 remote yes, idle yes pr1 on

[Stanimir]

Hi!
Sorry - look in /etc/lp/interface/pr1
for this parameter.
Regards.

/etc/lp/interface is a directory that should contain a file for each and everyone of your printers. Just find the one that you want to change and edit it to change the parm. If the parameter is set to a name, then you'll have to change /etc/hosts or the DNS, depending of where you have defined this name.

[K. Munk Kristensen]

Nop! the printer/IPaddress can not be found in the /etc/hosts file. So where does SAM get/hide the IPaddress? (-and is it safe to edit this file?)

[K. Munk Kristensen]

Yes! thanks - I have now spotted the printer1 file in the /etc/lp/interface directory. There is a comment in this file reading:
# lp interface for remote spooling.

But I can't find any IP address specified (or any parameter that could contain the IP address)...

[Marco Santerre]

find the parameter PERIPH= , it should be about 7 pages down, and should have something beside it. It should be your IP

If it is indeed a *remote* printer, i.e. the printer is configured as a *local* printer on a *remote* system, then you indeed have to remove and re-add the printer with SAM or lpadmin(1M).

If the printer is a *network* printer, i.e. you print *directly* to the printer, not via another system, then things are different.

And then there are network printers which act as if they are remote printers. For SAM/lpadmin you should treat these printers as *remote* printers.

So what do *you* have? I.e. printer manufacturer and model? How is it connected and to which system(s)? What (HP) software do you use for the printer? Etc..

[K. Munk Kristensen]

First of all it's a printer on a system of one of our customers I'm (trying to) manage??? I don't know exactly what make/model/kind of printer we are talking about. The printer is placed overseas ???but I guess it's a printer with a network adapter (like a JetDirect)

As I wrote earlier on SAM shows Type=remote - but when I Telnet the IP-address it seems to be this network adapter responding - not another system/host so it seems to be a *Network* printer:

# telnet
Trying...
Connected to
Escape character is '^]'.
Local flow control off
TallyCom+ PSIO

User:
Password:

Now I have Removed the printer and Added it again with SAM - and have to go through the same procedure on a couple of other hosts using the same printer???

Many thanks to all for advice

(Still a bit confused about this *Remote* / *Network* printer concept)

We have Tally Com boxes, they're little print servers just like JetDirect boxes.
I seem to remember I used to have to set the IP Address using arp within 10 seconds of turning the thing on. Although I believe they have software that does it as well (and better). Do I remember connecting using a browser like iexplorer?

As for the IP address, I set the host's IP address in /etc/hosts, this then tells it where the print server is (the print server is acting like a host with a remote printer on it).

Er as per usual I'm a bit slow on the uptake. I guess you've fixed your problem now.

[Gavin Clarke]

Here's a bit from the Tally Com Quick Installation Guide.

Which might help you to discover the default user and password, which may or may not help.

For future reference, if you configure your network printers via a hostname/FQDN, you won't have to adjust spooler files when one changes IP addresses. When you change /etc/hosts or the DNS zone, whichever is applicable, the name will then map to the new address and the spooler won't need to know.
