HPLIP with IPP

[Rafael Kawecki]

Hello,

I have a HP LaserJet Pro CP1025 connected over my router to the home network.
I did the installation on Windows XP according to the manual of the router and it works perfectly (as far as I could test of course).
On my Linux installation (openSuSE 12.1 and 12.2) I did the mentioned steps and have finished the installation successfully but I cannot print anything. Previously the same printer was connected directly to the computer and it worked without any problems. Now I would like to use the same printer from different computers.

What I did is following:
- in Yast installed a new printer
- connection over IPP (ipp://192.168.2.1:631/printers/printserver)
- installed PPD drivers (which I've used when the printer was connected directly to the computer)
- finished the installation and tried to print a test page without any result.

I'm not sure how to check what is the problem exactly, but I hope it's something simple :-)
Can somebody help me with this??

Best Regards,
Rafael

You wrote "HP LaserJet Pro CP1025 connected over my router"
and "connection over IPP (ipp://192.168.2.1:631/printers/printserver)".

What exactly means "connected over my router"?

Has the printer a built-in ethernet port and is connected via its own
network cable to the router box or is the printer connected e.g. via
an USB cable at an USB port at the router box?

In many cases the connection over IPP does not work reliably
for network printers, printserver boxes, and printing
via router boxes because those devices often do not
implement the IPP protocol correctly.

Only use IPP when the vendor of your particular device actually
documents official support for it (here the vendor of your router box)
and ask the vendor if IPP doesn't work with your particular router box.

See

The usual solution is to use another protocol like LPD
or plain TCP socket (a.k.a. Appsocket or Jetdirect).

Does HPLIP support networked printers?
Answer:
Yes, HPLIP supports printers that are directly
network connected (via a built-in Ethernet port)
or connected to a network via a JetDirect.
---------------------------------------------------

In other words:
HPLIP does not support it when a HP printer device
is "hidden" in the network behind a router box,
i.e when the printer is not connected via network
to the router box but e.g. via an USB port at the
router box.

I have following configuration at home.
My router (Speedport W723V Type A) is located in one place.
The printer (HP LaserJet CP1025 with only USB connection) is connected directly over USB to this router. This printer has only USB connection.
My computer with SuSE 12.2 is connected over normal LAN cable to the router. I have also two other computers, which are connected over WiFi to the same router. On one of them I run Windows XP and I can use that printer over IPP protocol. The configuration was pretty easy and according to the manual of the router.
So, this type of connection works in general.
Therefore I'm sure it works also on my SuSE computer but I'm just doing something wrong...
