just upgraded to Lion and my Oki Data 3400n won't print

I waited for the OKI 3400N driver update before upgrading to Lion. I installed the update on all three Imacs. The 2 Imacs witch are connected to the home network via ethernet see the Oki 3400N, install it and work fine. However, the Imac connected to the network via wireless access point will not find the Oki 3400N. It will see the 3400N@the other mac computers on the system but not seperately on the network. The wireless Imac also has no problem using my new HP printer which is connected to the network wirelessly. The 3400N is connected to the network via ethernet. I have tried reinstalls, reboots, redownloaded software everything I can think of.

What gives?

Saw this in another discussion and it worked.

Go to add printer (other since mine not listed)

Go to Internet Printing (IP)

Choose LPD protocol

Type in IP address for your printer

Name the printer

Leave all else blank (it found the software update for C3400N i had installed)

Bumping this discussion and describing my situation ... I have

• a C3400 on an ethernet network.
• one iMac (10.6.8) which owns the C3400. It works fine.
• a G4 laptop (10.5.8) which happily prints to c3400@imac-one.
• a second iMac (10.8.2) from which I still cannot send print jobs to c3400@imac-one, although it can see it.

I have followed most of the good advice here and even the "new" OKI stuff posted in 7/12, but nothing works.

I had several reasons for not updating imac-one to Mountain Lion, but all have vanished over time - except this C3400 issue. My suspicion is that it won't work at all if I update. Questions ...

1. For the time being, can I do something on imac-two so I can print to it without owning it?
2. If I update imac-one to Mountain Lion, can it still own the C3400 and use it?
3. If I update, can I still print to it from the laptop, which cannot be updated?
