I had some problems like these when initially setting up a C5180 (is networked but has no Wifi). The solution was simple: Before installing disable the AV and the Firewall. That's because the installer HP used was a fast one and it took too much time to reply to every question your Firewall asks and the AV also takes it toll. I tried it that way - BTW it was mentioned in the readme for the installer at that time - and lo and behold it worked. Never had a problem since.The online/offline problem: In the first place if the printer is not powered up it is offline no matter what you do, it is offline and stays offline. There's only one possibility to get it online : power it up and let it do its magic which will take a couple of minutes. (aka getting an ip address, doing its maintenance etc.) After that has been accomplished, the printer should be online and ready to be used. After a certain amount of time being unused my C5180 goes into sleep mode but stays online, no problem there either. SO when the printer is in a sleep mode and I need it, I just hit the print button is the application where I am in and after that the printer awakes and off it goes again.Secondly, if it still fails, it may be a firewall problem. I encountered that in vista when I was using the build in Windows firewall, I had to set some exceptions in the firewalls rules for particular HP files. HP has a document for my printer which explains which files to set as an exception in the firewall, maybe they do have a document for your printer as well.
still the same...
