Question about Printers & Copiers
The printer installs ok and works on first installing. However once the computer and router have been switched off (and obviously on again) it stops working and says printer disconnected - any ideas would be great
I was having the exact same issue for months and only now I have been able to resolve. You are correct. It is the firewall causing the problem. Your computer will send out a "keep alive" message out to the printer. I use AVG firewall and by default it blocks the UDP packet. Since the packet is blocked, Windows thinks the printer is "Disconnected."
In AVG, I changed the program C:\Windows\System32\svchost.exe from Block to Ask. Almost immediately the system asked to allow the packet. I did allow and now the problem is resolved. You only have to allow one time. I'm sure Windows firewall is similar.

I experienced this problem and found that my AVG firewall was blocking communication from my PC to my wireless printer. I found the AVG Firewall setting for an application called "Various System Services"(This controls the file C:\WINDOWS\system32\svchost.exe). From this "Application" it was a matter of adding an "Application Rule" specifying UDP Port 427 Inbound and Outbound, and setting this rule to "allow for all." Hit OK. Voila, printer works great!

If you are using AVG 9 and Vista and cannot scan using the HP Solution Center to access the scanner. The problem WILL be with the svchost.exe RULE assigned to the profile that you are using according to AVG. Edit this rule (find the first UDP "subrule") and add UDP port 427 to the remote ports "OK" list. You will probably already have 0-65K "OK" on the local list. And, make sure that acess is both ways. I have spent a lot of time dicking around with this one....

Wait4me put me on track to my solution....
My AVG already had a rule to always allow svchost.exe... but the printer was still not detected. I DELETED THE RULE.
Scanned for the printer again, and when the firewall detected the traffic from svchost.exe I chose ALLOW as a permanent rule. My problems are now solved. I don't know what was wrong with the original rule, it looks identical, but delete/recreate fixed my issues.

I have NO solution to my problem with this HP printer, HP will not help until I will buy extended warranty,and I just installed this printer two days ago, it doesn't work wirelessly or automaticlly, every time I can use it I have to hit the power bottun of and on to work and the USB wire should be connected to the pc. I am having amazing problems and I cant resolve it period.. And HP doesn't care to help us in any ways..Just they want money and resolving the problem is not guaranteed... RUBY

I wasn't having issues with the security at all, I am using mac os. I just can't let the two device meet halfway through..my computer is connected to the network and the printer as well as it generated a valid ip address. When I tried to install it, it is having issues that it can't find the printer on the network. I tried to reset the printer and connected back to the network and now the installation found it. I want to share with you the steps I did to reset it, here's the link How to Reset the HP PhotoSmart C4400 through the Secret Combo Keys. goodluck guys. my hp c4300 is just amazing.

My solution: Setup the network on the printer to pass by using the USB connection. Install Apple's ZeroConf / Bonjour / Rendevous / mDNS (yes, it's really called any of those) for Windows from http://developer.apple.com/networking/bonjour/download/ then use the "add printer" utility to scan for the local name of your printer; it's like HP00AB02.local. (usefull huh). When prompted for the driver for this printer, select it from the CD's *.inf files. Now you have a NAMED ADDRESS, which unlike the IP address won't change when you turn your router or printer on and off.
Auxillary Sollution: Firewalls ****. Uninstall them. Your router should be doing that job. If you travel with your pc (it's a laptop?) and connect to strange networks in the night or you invite people who may have been connecting to strange networks in the night to use your network instead of a guest wifi router, use only the Windows Firewall, because at least it won't disable all the windows file and printer sharing stuff.

You need to reserve an IP address so that each time the printer turns on it is given the same IP address by the router, otherwise the drivers have trouble finding it (badly written drivers)
Log in to your router and look for a setting for reserving IP's. It will be specific to the router so I cant really be any more specific.
I hate this printer, I have had so many issues due to problems with te vista drivers, total waste of money and my time. I still cant always get the scanner to work wirelessly and every 40 minutes the scan head moves on its own. So I have to have it turned off other than when I am using it. Not much point in wireless if I have to go to it and press the button each time I want to use it and then again when I am done.

Windows XP solution:
Ok, so the only reason i knew how to do this was because i used to dabble in some IT. Once you have the network printer test set to PASS you are only half done. Next you need to put the Driver's CD in and find the IP address (should be on your PASS test piece) from the printer on your network. In my case it was 192.168.1.101. I then went to "add a printer" to my computer. Pick Local Printer, uncheck "Automatically detect for....." and hit next. At the next screen, Highlight the "Create New Port" option. In the dropdown select "Standard TCP/IP port". Click, Next, then Next again. Enter the IP address from your printer (in my case 192.168.1.101) and the port will figure itself out. Click Next. It will take a second to find the IP address, and then, it will ask you for drivers for this device. Point it towards the CD-rom where you should have the Driver's Disc in. The rest is pretty simple. Hope it works!

Yup, I had exactly the same issue too.
I also manually set up the port for the printer to the IP address, which made it print wirelessly, even though the printer monitoring software, and HP solution Centre thought the printer was still "disconnected".
But, I found that even though I could now print, I couldn't scan - the printer gave a warning "USB or wifi network not connected".
After a phone call to HP, they got me running the install CD, choosing option "Add device", then "Using Network" (wifi), where I chose the printer. This set up a second copy of the printer, which had it's port pointing at the same IP address but where the port name also included the device serial number. So, this seemed a more proper way to set up the IP address. I could still print wirelessly, but still could not scan.
I turned the printer off and on, just to see if it needed to pick up the network that way. Unfortnuately, when it came back on, though I could still print wirelessly, HP Solution Centre could now no longer see the printer, saying "Disconnected".
I gave up at this point and am about to take the printer back to where I bought it.
