Photosmart C4780 says wireless is on but computers say printer is not connected

My Photosmart C4780 has always been temperamental with its wireless network connection; I have had the printer replaced once already and with both machines spent several days worth of hours on the phone to HP Helpdesks trying to uninstall and reinstall the drivers and additional software for various issues - either printer or scanner not working.
Now the problem is that although the thing itself says that the wireless connection is on and working fine; none of the computers on my home network (Two PCs running Windows 7 32-bit; and two Macs running OS X Lion) are able to connect to the printer; no matter what I try it keeps saying the printer is offline.
I would happily throw the thing in the rubbish bin to stop wasting any more time on it; but I have just bought 5 new (original HP XL) cartridges for it and would hate to waste those.
In fact the problems started when I replaced the cartridges; the alignment page at first refused to scan and when it did, it came up with an error message which unfortunately I can no longer remember exactly; something about the thing not being properly aligned and this may affect print quality. I am assuming that this is what caused the problems; although why this would cause the computers on the network to say that the printer is offline I have no idea. It has printed scanned images since then which came out fine; so the print quality can't have been that badly affected.
Anyway, the thing is too old now to be able to call the HP helpdesk again (all of about two years old!) so I really don't know what else to do - apart from binning it and trying to get a refund on the three unused cartridges. Oh, and buying a different make printer, obviously!
I have previously had a Photosmart 7350 which worked beautifully for many years, until I upgraded the computer to Vista and HP could not be bothered to provide updated drivers for it. The print quality of this one was what made me decide to go for HP again - a decision I seriously regret now!
Does anyone have any ideas of how to get the thing working again; at least until I have time to properly research an alternative?
Thank you

Thank you PrintDoc. I'm afraid I don't completely understand your instructions. I found the page you said to set a manual IP address, but then I got stuck:
When you say: "You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250" what exactly do you mean? All boxes on this page are completely blank; so what address should I put here? Put the same address as the printer currently has, only substitute another number (like 250) for the number after the last '.' in the printer's current IP address.
And when you say: "Enter your router's IP (on the Network Config Page) for the gateway." are you talking about the IP address that is printed in the confuguration summary underneath 'network name (SSID)' and 'hardware address (MAC)' as 'IP address'? Or would this be the address to put in above? The gateway address will be the same as the printer's, but will end in .1
Thank you for your help so far; please clarify this.

Photosmart C4780 not printing

I have a C4780 which has not printed since new - the paper feeds through but no print appears. I have tried both MS Office documents and Notepad.
I have tried it on both a laptop, with a wireless connection, and PC with a USB lead (both on Vista 32 bit).
Test pages print fine on lead (but not wireless test page).
Print and wireless utility diagnostics both reveal no problems.
I have power reset many times. I have also downloaded up to date software, and uninstalled and reinstalled.
Any help would be greatly appreciated. Thanks

Hi
Please check that the paper guide is flush against the paper in the input tray.
Also it may be useful to ensure that the printer is properly aligned. Check out this link (See solution 6 Step5)

Photosmart C4780 - Prints extra page even after HP driver update installed

With Mavericks (OS X 10.9.4) installed, I have noticed that completed print jobs remain in the print queue for my HP Photosmart C4780 when printing from Safari and Preview. If I want to print another (different page), I usually have to delete the previous (100% complete) job from the queue so that the printer will print (I seem to recall that sometimes, with a Google Chrome browser, this is not necessary). If I close my MacBook Pro's lid (which puts it to sleep) with a completed print job remaining in the HP queue, it will then print again for a second time.
Today, I installed the driver update below, but the problem did not go away when I tried to print from Safari and Preview.
Critical HP Print Driver Update to address printing of an extraneous page - 2014-01-31 , Version1.0.0, 10.56M
Any ideas of how to solve my problem?

Sure - restart your router, your printer and your Mac. It should print faster (especially with a router restart).

C4780 still says "printer off line" after troubleshooting

HP Photosmart C4780 Inkjet printer
Mac operating system
"printer off' line"
just moved and re-set up computer with same router....using printer wirelessly as before

Well, you did not say WHICH Mac operating system, so let's try this:
Reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

HP Photosmart C4780: Can't hook up wireless..Please Help

I just bought a brand new IMAC and a brand new HP Photosmart C4780 wireless printer and a new Linksys WRT160N wireless-NBroadband Router. I go thru all the steps to set up and than get the error message the configuration failed and the software was unable to configure my device. The error message says :
Ip Address: Failed to retrieve IP
Subnet Mask : Failed to retrieve IP
Default Gateway : Failed to retrieve IP
Preferred DNS Server: Failed to retrieve IP
Alternate DNS Server: Failed to retrieveIP
I am clueless where to go from here. Can someone please help.
Thank You
Joe

The Linksys WRT160N has WPS (Wi-Fi Protected Setup). If you are using WPA-PSK encryption (recommended), then you can easily connect the C4780 to your wireless network using WPS:
1) On the Linksys router, press the WPS button that is top of the case just under the Cisco label. When the LED on the button starts to blink, then the WPS process has started.
2) On the C4780 printer:
press the Scan Button
select Wireless Menu
select WPS
select Push Button
The printer should connect.
Since you have a new iMac running Snow Leopard, then all that is left to do is to install the SW. Open the Print & Fax applet under System Preferences and press the [+] button. Highlight your printer and press Add.

Error message: Printer cartridge problem

I'm copying only at the moment. A small stack of papers.
Suddenly the printer seemed like it was taking too long on a page, and it just kept staying in the same position but nothing was happening.
Finally I tried to shut it down but it wouldn't shut down. It said, shutting down, but it wasn't.
So I unplugged it and waited a bit, then plugged it back in.
Then it appeared to be OK but when it started the copying process again, it stopped and gave that error message.
Is it something as simple as it's out of ink? But I don't think it should be. It wasn't showing that it was low.
Any suggestions, anyone?

Hi melegay,
Welcome to the HP Support Forums! I understand you were trying to copy on your HP Printer and the paper was not feeding, you did a hard reset now your printer's front panel is saying 'Printer Cartridge Problem'. Can you please let me know the Exact model of HP Printer you are using?
Please start here: 'Ink Cartridge Problem' Message Displays on the Product Control Panel. Follow these steps in the order presented to resolve the issue. When one of the steps resolves the issue, there is no need to continue troubleshooting.
If you are still getting the error message let me know and leave me with the requested information.

WiFi connection problem from HP Photosmart C4780 to MacBook Pro

I have an HP Photosmart C4780 that will not connection to my MacBook Pro. I am operating on the Mac OS X 10.6.8. It was working just fine when I was using my Apple Airport to project the WiFi in my house, but I recently bought a Apple Time Machine to back up my system and have a main networok and guest network for the house. When I switched to the new device, I am now unable to get my printer to reconnect via WiFi. I have downloaded all of the recommended software from the HP site.
When I click on set up wireless connect, it starts the first step to find the device and then I wait and wait. It just sits and spins and never finds the device. Yes I have it plugged in and turned on. I did not have any problems with this prior to switch the router for the WiFi so I am guessing it has to do with that, but I am lost on what to do. Please Help

Welcome to the HP Forums FlyGirl_1350,
I see by your post that you now have the Apple Time Machine and aren't able to setup the printer again on the network.
I can help you with this issue.
Follow these steps to restore your product's network default settings. This will clear out the old router encryption.
Touch the ATM button () next to Wireless / Scan.
Touch the ATM button () next to Wireless Menu.
Touch the ATM button () next to Wireless Settings.
Use the up and down ATM buttons () to select Restore Network Defaults, and then press OK.
Touch the ATM button () next to Yes to confirm your selection.
Make sure the computer is connected to the Main Network Name and not the Guest Network name.
Vice Versa. Sometimes the printer won't pick up the Guest Network to configure the wireless.
Run the setup again.
This document provides steps for setting up the printer on the network also.
Installing the Printer Software for a Wireless Network Connection (Using an Access Point).
If you are still having issues then power cycle all the devices in this order, power cycle the router, wait till it is back up again, turn the computer off and on again, turn the printer off and disconnect the power cable for 30 seconds, then reconnect it again.
If there is anything else that I can help you with just let me know.
Have a nice day!

HP Photosmart C4780 problem with wireless connection & firewall

Hi
I am trying to connect my HP Photosmart C4780 to my wireless network at home.
Each time I try to configure my printer to my wireless network I keep getting the following HP Network Diagnostics Error Message:
Problems may exist with network functions of the printer. Please try to fix the issue then click Retry or click Next to continue. See details below.
Your printer is unable to communicate with your printer at 192.168.1.69. This may be caused by firewall software. If you are using firewall software verify that UDP port 427 is unblocked for both inbound and outbound traffic.
Your PC cannot communicate with your printer at address 192.168.1.69. Check all cable connections. Check that the printer, PC and router are powered and connected to the network.
MY QUERY - I have AVG 2011 security software installed on my laptop which I presume contains firewalls. But I do not know how to "verify that UDP port 427 is unblocked for both inbound and outbound traffic". How do I do this?
i am not a tech expert so would appreciate as much help as possile with this as right now I cannot use my printer as it keps showing as Offline.
Many thanks

Go into the AVG menu and simply disable the firewall and retest.

Photosmart c4780 will not print in color

Brand new to forums... I am using a MacBook Pro, OS 10.6.8. I recently bought a used photosmart c4780. The owner said it only prints black. When I set everything up, it wouldn't print at all, as the black ink was depleted. I replaced the black cartridge and now it prints. However, even though the color supply levels are at about half full, it will not print in colorI receive no error messages. Have tried different settings in the Print dialog options to no avail. Have not been able to find anything online that addresses this exact issue within the parameters as I've described them. Any help appreciated.

Photosmart C4780 Windows 7 64bit connectivity problems

Is there any link where I can download the full set of drivers to make Photosmart C4780 work on Windows 7 64 bit?
Can I buy anywhere a CD contaning all required drivers to make this printer work with Windows 7 64bit.
I have installed all updates from HP but I still can not make it work. (Win 7 32bit does recognise the printer and jobs are printed without any issue).
In fact, I got so frustrated with the time I have lost over this issue that I bought a new Cannon printer. It worked instantly so it sloved the immediate problem for me. But it would be still nice to get the HP printer working.
Thanks,

Hi,
The drivers for your printer can be found on the following page:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=da&cc=dk&dlc=da&sw_lang=&product=3794...
You can download the software needed to make your unit run from that link.
Please let me know how it works.
