How do I put a network Laserjet that is off-line, back on-line

Hello Experts -

I've got a HP Laserjet on a home network. One of the computers on the network was recently replaced by a computer running Windows 7. At the sametime, the network was added to "Homegroup". There are now two computers on the network running Windows 7.

Now the printer won't print. I can see it on the network, but it says the printer is off-line. How do I put it back on-line?

hi gbmcneil,
got a few question for you:
1- does the other computer (that is not recently upgraded but also running windows 7) can print?
2- what is the model of you HP printer?

-you can download "HP Home Network Diagnostic Utility" from HP and diagnose the problems: http://h30434.www3.hp.com/t5/Printer-networking-and-wireless/Having-trouble-with-a-network-printer-The-HP-Home-Network/td-p/255609

Hi OP -

Here. I've got to go out for a couple of hours. Some emergency.

Let me do me do some research at my end and I will get back to you. I will download the HP diagnostics before I report back in.

I can see that I have to re-install theLaserjet  printer on my new Windows 7 machine. At the moment it is not cooperating. I think I'm going go deal with this in the morning. Talk to you all then.

Okay. I am back at it. To review...

Initially I thought this was a simple problem of putting my HP Laserjet back "on line". Then, I realized that the computer computer that I upgraded to Windows 7 formerly was the computer that the Laserjet was "attached to" when things were working. Obviously, by installing Windows 7, I destroyed the connection to the printer.

The other complication here is that when the Laserjet was physically re-connected to my little network run by a Linksys router, I had to jump thru all sorts of hoops just trying to get one computer to be able to see and use (share) the C:\ drive of the other computer. This was a topic for the Experts at the time. I solved this problem by creating a network called "Homegroup". See -

http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Q_26892817.html

As it stands now, I have tried unsuccessfully to re-install the Laserjet on the new Windows 7 computer. The only other computer on the network at this time is also running Windows 7. The Laserjet is only a couple of months old. Its an HP P4014n. When I originally installed it back in December, I had no problems, but that is before I embarked on upgrading all my computers to Windows 7 (and adopting the name "Homegroup" for my network).

The attempted HP Laserjet installation ends saying that the install failed. Maybe it can't see the new "Homegroup" network that is a part of Windows 7 (i.e., the install disk might have been created before the concept of "Homegroup" was ever envisioned).

I am going to look around on the HP website to see if they have a new P4010 / P4510 Series installation disk. Outside of that, I'm stumpted.

We have some progress here. As indicated above, I went to the HP website and found some new software for my P4104 Series Laserjet. It was the "HP Universal Print Driver for Windows PCL6". It was dated the 18th of February, 2011 - which made it only one month old.

After this driver was installed, I was able to get Computer2 to print. Computer2, you will recall, is the computer where the networked Laserjet was originally installed.

Now, presumably I have to go to Computer1 and install the new HP print driver again there. I say this because Computer1 can't see a printer on the network at this time without doing anything more.

No. I did not install the print driver on Computer1. I went to Devices and Printers and added the P4014 Laserjet. And, kaboom, it all worked.

Thanks to everyone for their help. The key seems to be getting the lastest drivers from HP.
