Help With a HP photosmart printer.. 10 points for best answer..?

maybe it's need just to update the software and driver for your printer. try that and restart your pc.

more people have problems like you with this ; for more details visit HP (official) forum http://h30434.www3.hp.com/t5/Printer-All-in-One-In... down of page you find a solution !

good luck !

To solve it, I turned DHCP off on my router and then tried connecting the printer to the wireless network. This time it connects fine but you still can't talk to it because it doesn't have a proper IP address. If it still doesn't connect properly, try turning WPA/WPA2/WEP off on your Access Point. Leave it completely open for a moment until you can reach the web interface (as below).

To fix the IP issue, I then went into the Settings menu on the printer and printed the "HP Network Configuration Page". Note that under the Wireless menu option there are a couple of different "Print Network Test Page" options. I believe it's the 2nd one that I selected. You'll know you have the right one when it prints out the page with the following info:

IPv4 IP Address

Subnet Mask

Hostname

Default Gateway

Primary DNS

etc, etc.

Take note of the IP Address from the printout above and the Subnet Mask. My IP was 169.254.73.5 and subnet mask 255.255.0.0. Now I manually configured my computers IP address to be similar (within the same subnet): 169.254.73.10 with the same subnet mask.

Now you can load up the web interface of the printer using http://169.254.73.5/ in my case. (You should also be able to ping the printer at this point too). In here you have a Network tab where you can now manually set the IP Address of the printer. Set the address you want it to be in your network (in my case 192.168.0.3 with a subnet mask of 255.255.255.0 and default gateway 192.168.0.1 and dns server 192.168.0.1).

Once I clicked OK I changed my PC's IP back to normal, and I can now reach the printer on its IP address set above. YAY!

The great thing is, in the web interface you get a million more options to play with. You can manually set the IP address, gateway, DNS, wireless settings such as WPA1/WPA2 AES/TKIP Encryption, WPA Passkey, etc. So if you had to set the Access Point to completely Open, setup the encryption again and put the passkey in here. When I did this I had to go back into the Settings menu on the printer LCD and select "Disable Wireless" then "Enable Wireless" to force it to re-join the network.

Finally I went into the Settings menu again and Updated the software on the printer. I don't know if the new software fixes the bug or not - I haven't tested it (can't be bothered!).

I downloaded HP Driver and Software and also received HP updating program this checks your software is up to date regularly.
