Unable to print after new router installed

After having a new router installed by our cable supplier, I have been unable to use my printer with my laptop nor my desktop computer. Do I need to uninstall and reinstall my printer on both computers?

Printer no longer detected after new router installed. Tried everything. Please help!!

I have a Photosmart 2575 printer which has worked well for a number of years. It has a wired connection to my router.
Recently I installed a new router (Sky fibre hub) and now the HP software (and any other printer/scanning software) is unable to detect the printer on my network. This is odd, because both my desktop (wired network connection) and my laptop (wireless network connection) can see the printer and I can install it using the standard windows 7 functionality. I can also browse the embedded web server, so I know for sure that my printer is on my network and accessible.
But despite numerous attempts to make the HP Solution Center software to work I am unable to print/scan etc from that software. I have tried many different "fixes" including full Level 4 uninstalls before reinstalling the software, resetting the netowrk settings on the printer, deleting the printer from everything on the network etc etc but nothing has worked.
I have tried using the HP Print and Scan Doctor software but that doesn't help.
I am totally mystified by this apparent lack of connectivity.
Can anybody help, PLEASE PLEASE!!

This question was solved.
View Solution.

Success at last, but only after many hours of trawling through HP and Microsoft forums, and numerous attempts to make the connection!
But here's a summary of what I did for anybody else with this issue:-
1. I meticulously removed every trace of anything to do with HP from my PC and disconnected the printer from the network router.
This requires numerous "level 4" uninstalls to clear any previous falied installs and deleting everything in the temp file afterwards:-
1. Press the Windows key, and the letter R
2. Type %temp%
3. Press Enter, or click OK
4. Open the 7z folder
5. Open the util folder
6. Open the ccc folder
7. Double click the Uninstall_L4
2. Using Control Panel_Programs and Features, uninstalling anything left that might be HP related
3. Carrying out a disk clean up using Start_Accessories_System Tools_Disk Cleanup and repeating this for system files
4. Follwing the procedure found from the following link to check that the print spooling is working, and that any dependencies are "started":-
Link to post
In that thread there is a further procedure to follow which requires opening a command prompt in administrator mode and carefully inputting the command line
sc config spooler depend= RPCSS
(note the space after the = but not before)
5. Running msconfig.exe and on the general tab, clicking "selective startup", unchecking "load startup items", then on the services tab, hiding all microsoft services, and deselecting all items [remember afterwards to re-run and go back to a normal startup!]
6. Restart PC
7. Disable Firewall [remember to enable afterwards]
8. Launch Internet Explorer (I had previously been using Chrome)
9. Download AIO software from HP website
10. Run and connect printer when prompted (making a note of the printer's IP address)
11. The networked printer wasn't found immediately, so click on advanced and then input the printer's IP address
12. Success - the printer was finally detected and installed correctly.

HP C7200 printer/scanner not working with Mac after new router installed.

I recently had my DSL modem go out and replaced it with a combo modem/wifi router. Since the install, my mac can't detect my printer. If I install it via the printer's IP, it'll detect ink levels for a day or two, but still won't print, and won't even detect the scanner. It says the printer is off-line when I try to print. I've rebooted everything, reset the printing system, downloaded updates, and downloaded the latest HP software. Nothing helps. So much for "just works".
My little Windows 7 computer was totally trouble-free after I reinstalled the printer.

If the printer does support Bonjour and it does not appear in the Default Add Printer view then I would say that the Mac is set to a different subnet to the printer (and the Win7 PC). This could also explain why you can add the printer via IP but it won't print.
If the Mac is definitely on the same IP subnet as the printer then check you don't have an application running that could block Bonjour.
With regards to IP queues, ensure you select HP Jetdirect rather than the default of IPP (Win7 will be using Jetdirect which is known as Port 9100). Also, some drivers cannot be used with network connections. If the printer supports Postscript then try a Generic Postscript printer to test. If it doesn't support PS but supports PCL then there is a Generic PCL Laser driver you would try.

Adding Canon MP620 printer to network after new router installed

Just changed routers in order to get fibreoptic. all devices easily connected apart from Canon printer. Have re-installed drivers and followed directions but laptop ( windows7) just can't detect the printer...?

This is device specific problem. Try to contact Canon directly for help
http://www.usa.canon.com/cusa/consumer/standard_display/contact_us_consumer
Otherwise I would disable firewall and analyze the nework communication. If there are any error messages or error IDs in Event log (or even bad installation yellow question marks in device manager), then follow the appropriate troubleshooting steps.
It is useful to provide as much information as you can do so we can suggest repair steps. Sometimes it is better to remove driver with driver installation package and then reinstall the driver. (Otherwise some remnants of old driver software may case problems.)
Also optional update may cause ghost printer installation on different IP address.
Hope that the IP address pool is not exhausted and Canon can obtain IP address. (Ping may or may not work.)

HP L7780 Completely locks up after new router installed - MAC

I had to replace a Linksys router WRT54G with a newer model WRT1900AC Dual Band. The printer was working fine with the old router. Now I use the Wireless Wizard to set up the new router and it locks up. The only way to "free" it up is to turn the router off and turn the printer off, then turn the printer back on and turn the wireless radio off. I am using a Mac running OSX 10.8.5. I see in other forums to update firmware but that appears only to be on the windows side.
Any help is appreciated. I spent a lot of money on this printer to have to junk it.
Thanks!

Hello @3408RaissaS,
Welcome to the HP Support Forums!
I understand that you're experiencing issues when attempting to configure wireless on your HP Officejet Pro L7780 All-in-One Printer with your new wireless router. I would like to assist you today with resolving this issue.
Now, due to the age of your printer there is no Firmware Updates available for your model of printer on your Operating System. Therefore, this will not be an option for your specific unit.
Because the printer worked wirelessly with your old router we know that the wireless card within your printer is functioning. Therefore, there may be a setting within the router that needs to be adjusted to allow for your HP Officejet to connect and communicate wirelessly.
Just to confirm, at which point does the printer freeze up (after you select your network name, enter your password, or when it tries to connect to the network)?
Because you're now using a dual band router it is crucial that you are connecting your printer to the 2ghz band. Printers are not supported on 5ghz connections. This means that the computers that you want to use wirelessly with your printer must also be connected to the 2ghz band. If you're not sure how to check what band you're connecting to, you may need to speak with the router manufacturer.
Please respond to this post with the answer to my question above. Once I have a bit more detail I will be happy to guide you towards a fix. I look forward to hearing from you!

My mac isnt recognizing my printer after new modem installed

We got a new modem and now my mac doesnt recognize my HP Envy 4500 wireless printer. I have reinstalled the printer several times and it works for about 2 min then it says offline. Even when I reinstall it doesnt appear on the list of available printers and I have to use the set up wizard for my computer to find it. I have done all the mac updates and have all the right drivers. Our non mac computers still work fine and mine did too until the new modem. Any suggestions?

Hi @nmoff,
Welcome to the HP Forums!
I noticed that you are getting the error message "The system cannot find the specified file". When reinstalling your HP Photosmart c6180 on Windows 7. I am happy to help!
Please take a look through this post, Re: Install Error "The system cannot find the file specified" (hpzprl40.exe). (Even though it's for Windows 8 and a different printer these steps will work for you as well).
Hope this resolves your issue, and have a great day!

NP Officejet H470 - willl not print after new cartridge installed

Changed my black cartridge and now will not print at all. Document shows briefly in printer dialogue box but then disappears. Printer makes a noise like it wants to print but then nothing happens. Printed fine before cartridge change! Any ideas?

I bought a new unit. First thing it would not work. Pause light and start light flashed. finally after much research on HP site and elsewhere I solved it myself!
I found a part loose in the unit! Open the ink door, see a 1/8" +/- diameter rod under the print carriage, look at the right end, there is a white part that should be down and probably should click into place. Mine was up at a 45 degree angle. It went down easily, but did not truly click into the receiving hole, however it was enough that the printer worked!
The left side was down, but yours may bear checking.
HP puts you through all the testing stuff, but fails to rememder that printers are electro-MECHANICAL devices and can fail on the mechanical side.

Frustrated and Need Help with AE after new router installed

My AE worked fine on a previous router that ran through a modem. I now have a 2 Wire Modem-Router combo and cannot get my computer to recognize it. I am running Windows XP. I have plugged the AE base station directly into the router and configured it but, as soon as I disconnect the ethernet cable, it stops working. I have tried to join a wireless network in client mode but my computer, since it does not have a wireless card only a router, cannot see the base station. Which way do I go? Do I setup the base station while connected by ethernet cable or do I try to setup in client mode wirelessly? If while connected by ethernet, what settings? My routers is DHCP and does have a password associated with it?

Issue was addressed in another dicussion.

HT3917 My apple wireless keyboard is not working after new batteries installed

My apple wireless keyboard is not working after new batteries installed.

Do you get a steady green light to say there is a connection. If not, are the batteries the right way round. Do you have a monitor to tell the batteries strength. Is there a reading. Are the batteries good quality ones, Duracell, Energiser or Apple rechargeables.

HP 1300n wouldn't print after SL was installed

My HP Laserjet 1300n connected to a home ethernet network wouldn't print after SL was installed. My fix was to "add a printer", press the IP icon, use protocol HP Jetdirect - socket and enter the IP address for the printer which I obtained by manually printing the configuration page from the printer (holding the go button on the printer for 5 seconds). I'm a novice, but the printer seems to work fine now.
It is a shame that such a "finely tuned" product would require us to spend a couple hours searching through a forum to seek a solution for something as fundamental as printing.

I tried Software Update but the dialogue box said there were no updates available. Maybe I didn't do something correctly.

Unable to print after installing the new Quicktime upgrade

I can not print to my Epson printer after installing the new Quicktime upgrade on my PowerBook G4 (1.67 GHz, OS X Version 10.4.11). I have re-installed the driver from Epson (several times), and have safe booted and reset my permissions but it will not print. My printer is a Epson Stylus Photo R1800. When I print, it just gives me this message... "Looking for Printer 'EPSON Stylus Photo R1800' "

Latigna, welcome to Apple Discussions.
Here's a similar problem on the same Epson printer. http://discussions.apple.com/message.jspa?messageID=8928421

HP printer 5510 not printing black ink after new cartridges installed

having an issue with the black ink not printing at all..Brand new HP cartridges. cleaned screen with hot water vent is open

Hi 6043kmb,
Welcome to the HP Support Forums! I see you are running into some print quality issues on your HP Photosmart 5510, you are unable to print in black ink after replacing the cartridge.
I would like you to continue here: Printer Does Not Print Black Ink or Color Ink, or Prints Blank Pages, I understand you may have done some of these steps already but I need you to complete all steps in order to resolve the missing black issue you are experiencing.
Please note: There are three printhead cleaning stages. Complete all three stages if necessary. If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last (third) cleaning stage to start the first stage of the cleaning process over again.
If you are still unable to print in black ink, I suspect the issue may be the printer and not the cartridge. Please let me know which Country/Region you are in as well as the product Warranty status: HP Warranty Checker
I hope to hear from you soon.
Thanks,

Unable to Print After Installing Adobe Acrobat Reader Upgrades.

. What software version of Abobe Acrobat Reader should be used for an HP PhotoSmart Plus printer? I currently have Adobe version 9.3 installed. I receive pop-up notices to install new Adobe Acrobat Reader software upgrades. I have installed the software upgrades and then my HP PhotoSmart Plus printer was unoperational. I deleted the Adobe software upgrades and my HP PhotoSmart Plus printer began to operate. I contacted HP technical support and was told there is no compatibility issues between Adobe Acrobat Reader and HP All-in-One Products. It might be a problem with the specific Adobe software upgrades. HP requested that I contact Adobe support for problem resolution. Has this problem ever happened to you? Any problem resolutions would be appreciated.

Unable to print with new installation of Adobe Reader X

Yesterday I installed Adobe Reader X on my Dell laptop running Windows XP. After installing, I was unable to print to a HP Laserjet 4700 printer (only printer I tried). I rebooted my laptop and tried to repair Adobe Reader and I still can't print. I uninstalled, rebooted, and re-installed Adobe Reader X and it still won't print. When I click on the print button it just locks up with the hour glass symbol running (only locks up Adobe Reader). I have Adobe Acrobat 9 full version on my computer also and it works fine printing the same documents (a newspaper article without graphics) to the same printer.
Any ideas what could be happening and how to fix it?

Ditto on Darrenz16's problem. New WIN7-64 Home Premiun system with Adobe Reader 10.1.2. Reads several files, then starts locking up when I try opening new files. Seems like Reader is failing to release some resource and eventually running out of whatever it is. Rebooting seems to help temporarily. Never had this problem on previous systems. A set of good examples are the .pdf files at the bottom of this page: http://www.hussman.net/weeklyMarketComment.html
I can open a few, but then Reader locks up trying to download the files.
