Ipad rocognises wireless printer but needs a password

Hi, please assist.
Firstly I dont have a desktop computer.
I am attempting to hook up my ipad to my new hp 2540 for direct wifi printing and having great difficulty.
I am seeing on my wifi list on my ipad that the device is recognised but it is requesting a password?
I havent been given a password...please advise what I can do...please no demo videos for other model printers.

Hi @Dogwallop,
Welcome to the HP Support Forums. I understand that you would like to learn how to find the password to the Wireless Direct network your Deskjet 2540 printer is broadcasting.
You will need to print the Wireless Direct Information Page to get the password. The steps can be found on page 53 of your User Guide.
Please let me know how it goes.
Regards,
Happytohelp01

IPad recognizes my hp wireless printer but doesn't print. Why?

iPad recognizes my HP wireless printer but still nothing happens when I press print. Why?

If your using the option at the top next to the address bar to print, that the box with the arrow, that only looks for airPrint printers. That will not work on your printer.
They do however have apps that allow you to print to your printer, you just need to get one from the app store (read the reviews before downloading the app).
I use the app "print n share" but I can't recommend that one or say its good or bad, it works for whati need it for that's all. You would need one that does what you need and works for you, that's why I say to read the reviews.

I can print from my PC to my wireless printer but not from my ipad. What should I do?

I can print from my PC to my wireless printer but not from my ipad3. How do I cure this problem?

If it's not an Airprint enabled printer, you need apps like:

Remove the toner cartridge and gently shake it from side to side while holding it level (in the position it is in while in the printer). Re-insert the cartridge, restart (power cycle) the printer. Then restart the Mac and test.

Just installed my B110a works ok for normal wireless printing but i cannot print apps and on ePrintcenter is says NO CONNECTION, how do i solve this?

Hello schmittl,
Please let me take a moment to say "Welcome" to the HP Forums.
I hope you enjoy your experience!
I see that you are having an issue when it comes to scanning to the computer.
The error that appears when attempting to scan is accurate. I suggest that if you are using a anti virus protection or firewall, you disable the protection and reboot the computer and the printer and attempt your scan again.
With the anti virus and/or firewall disabled, please fun the HP Print and Scan Doctor once again as well.
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Thank you for your time.

HT1695 I am trying to print wirelessly and get no air printer found. I have a new hp 3523 wireless printer but can't make it work with the new iPad. Do I need a special driver or is there another way for it to work

How do I set up so I can print wirelessly to my hp wireless printer.

Hi,
The printer do support AirPrint (the HP Deskjet 3525 is part of the 3520 Series).
Make sure your printer connected to the same router as your iPad and it shold be listed..
Be aware that you need iOS 4.2 or higher and your router should support Multicasting for AirPrint to work..
If the printer isn't listed please clarify your router brand and model, some routers don't offer Multicasting or have the protocol disabled by default.

Why can i not get my ipad to recognize my wireless printer but my apple desktop works with it

Why can I not get my ipad2 to print from my my wireless printer that i use for my apple desktop

It's also possible that your wireless printer will work with a minor OS tweak if you're on Snow Leopard OS X 10.6.x. Your Mac system must be on for printing to occur. (I haven't tested with Leopard 10.5.x or Lion 10.7.x)
Details are found in this Apple Support Communities thread begun in November 2010

I've been using it to print to a Canon MP560 wireless printer and an HP LaserJet 1320 USB-to-Mac printer from my wife's iPad 2 since the first day she received it for both photos and documents. Duplex printing to the Canon does not seem to be supported.

Solution to Ipad/ Airprint wireless printing problems

I recently spent several hours trying unsuccessfully to get my ipad mini, IOS7.1, to print to an HP7525 printer using the airprint feature built into both units. I tried every trick offered on many Apple and HP forums but to no avail. I then discovered that my router, an ASUS RT-N1 3U does not properly support the Bonjour packet protocols which are essential to Airprint. So I bought a new router, the Canadian D-Link AC1200 (model DIR-860L), hoping it would solve the problem. It worked like a charm instantly. The Bonjour printer wizard now had the HP7525 in its list of printers and my IPAD mini could now print my Foreflight aviation charts, as well as anything else. It also seems to have solved another HP7525 problem whereby the wireless link goes down after 5 minutes and the printer has to be rebooted every time you want to print something. The link now stays up permanently!. I just hope my good fortune in solving these problems can be of use to others.
My PC operating sysem is WIN 7 64 bit.

These settings are for setting up your wireless printer to stay connected to your router, keep wireless devices better connected and make your router secure and hack proof.
1. Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual).
    This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this
    first if needed. More Wireless Printing help is here.
2. Verify in the printer that 'Auto Off' is disabled. Use the Embedded Web Server (EWS) by going to the
    printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer
    Assistant, Printer Home Page (EWS).
In the router: (Refer to your router manual for information)
3. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest.
4. Set router to 20Mhz only, or 145Mbps depending on router.
5. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
6. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your
   system now and helps with wireless connectivity (if you want to know why, search the web).
7. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.
8. Save all settings. Power off both, wait 2 mins. Power on router wait 2 mins.
9. Power on printer and verify it reconnects to router.
Windows 7/8/8.1   Is Network Discovery on or off?
Control Panel/Network and Internet/Network and Sharing Center/Advanced sharing settings.
Under Home or Work (current profile) / Network Discovery.
Select "Turn on network discovery" and save changes.

Wireless printer wont accept my password...help!

I have am iMac OS 10.5.8. I have an Airport Extreme. My connection to the internet is via cable ..erethenet. My husband's computer is wireless and he connects via the Airport Extreme. It works fine for him and it works fine for our laptop.
I recently bought a HP Photosmart eStation C510a which is a wireless printer. The printer is connected to my computer via usb cord. I spent 3 hrs with HP tech trying to resolve why the printer wouldn't accept the password for the airport wireless connection. He finally said it was probably a bad zeen (which is like a small detachable computer on the printer). I exchanged the printer. Now I am in the same situation.
When I try to set up the printer, I get to part about entering the password and it won't accept it. I know its right. I went to keychain and checked it out for sure and it is correct.
My Airport Extreme is at least several years old and I haven't done any updates. Should I and which ones. Does anyone have any suggestions?
I have spent hours on this and am at my wits end. i will be the first to say that I am not very savvy the ends and outs of this sort of thing.

Hi...I called HP again today. They gave me a list to go over with Apple. They are 1. Look for fireware updates. (I was so rattled when I first posted that I didn't realize that updates were on automatic) and all are updated. 2. OPen port 9100tcpudp 3. Change encryption to WPA 128 bit and 4. Allow printer through any firewall (firewall is not turned on.
The AirPorts do have firmware updates over time and they may include updates to the AirPort's NAT firewall, but there are no specific updates just for the AirPort's firewall so item #1 would be a bit meaningless.
However, when a wireless printer is connected to the AirPort, all communications do NOT go through the router's firewall as all of these communications are on the local network. Only if you were trying to access this printer from the Internet will these same communications be required to go through the firewall.
For item #2, again this would only be of interest if you were trying to access the printer from the Internet. It would serve no purpose when accessing it from the local network.
For item #3, I would be concerned that this printer does not support either WPA or WPA2 for wireless encryption. Their recommending that you switch to the basically outdated & unsecure WEP security would not be something I would agree with and would recommend against.
Finally, for item #4, this may apply to a software firewall used on most computers. Just like the router, OS X & Windows operating systems provide a software version of a firewall on the computer itself. Most are enabled by default and it may be possible that the reason you are unable to print to this printer is that the communication between the computer and the printer is being blocked by this firewall. For OS X, you enable/disable this software firewall via System Preferences > Security
So I called Apple tonight and they said my Airport Extreme is obsolete and I needed to buy a new one.
Unless your AirPort is one of the 802.11b AirPort Base Stations (Graphite or Snow), it shouldn't be considered obsolete and there shouldn't be any reason why this printer is unable to connect to it.
Just so I am sure which version you have, please look at the following Apple Support article and let me know which one you have.

Does iPad support wireless printing

I see that the new iPad has iPhoto can u connect iPad wireless to a printer?

It does support wireless printing. The printers that are listed on this page support AirPrint (the iPad and printer just need to be on the same wifi network for AirPrint printers) : http://support.apple.com/kb/HT4356 . If your printer isn't listed then you will need an app - the printer manufacturer may have their own app in the store that supports it, or there are a number of third-party printer apps.

HP LaserJet Pro P1102w printer "Ready" for wireless printing, but gives "error -- printing" message

This P1102w printer was configured for wireless printing from two computers (WinXP and Win7), both with a network sharing designation, and all functions worked perfectly:
Printing from the WinXP computer directly, and from a networked Win2K computer as a guest.
Printing from the Win7 computer directly, and from a networked Win2K computer as a guest.
Windows Printer Test Pages were printed from both installed computers, showing correct computer names, the printer name, Port names (IP addresses), Data format (IMF), Driver information, etc.
Several days later (after new boots), the WinXP computer showed printer status as being "Ready", along with the correct printer "Type" (HP LaserJet Professional P1102w), "Where" (IP address), and "Comment" (network printing). When a print job was submitted from Microsoft Word, the control-panel printer window first showed the message "printing", and then the message "error -- printing". Nothing was printed. The same results occurred when a print job was sent to the WinXP computer from the networked Win2K computer. HP’s troubleshooting routine did not identify the error, its cause, or what can be done about it.
Successful printing continued, as before, from the Win7 computer directly, and from the networked Win2K computer to the Win7 computer as a guest.
The printer’s blue “i” network indicator lamp is lit, and all three computers continue to communicate through the hub to each other and to the Internet.
HP’s printer installation program was executed on the WinXP computer, using the “fix” option, but nothing changed. The installation program was executed again on the WinXP computer, using the “new install” option (without removing the existing P1102w installation); the “browse” function saw the network, but no printers were found, and the installation could not be completed.
This is very perplexing. Any suggestions?
PS: The same problem occurred once before, and it was fixed by resetting factory defaults on the printer, hard wiring the printer to the WinXP computer through a USB cable, re-installing the printer’s wireless settings from HP’s installation disk, and repeating all of the networking and sharing setups on all three computers. This is a lot of work that is not worth repeating, because the successful results have not been permanent.

To: Neonskeleton,
Thanks for your response -- especially because you are an HP employee!
My Win2k machine does not use HP software, nor communicate to the HP printer. (HP did not write a Win2k driver for the P1102w -- and evidently no one else has done this, either.) My WinXP and Win7 machines use their HP drivers to send print jobs to the P1102w wirelessly, and both machines have the P1102w set up as a shared printer. Then, when I connect to those machines as a "guest" and submit a print job to those machines, those machines receive the print job and then communicate with the printer using the proper installed printer drivers.
Everything worked great with this configuration, until suddenly the printer was no longer responsive to ANY jobs coming from the WinXP machine, even though there was a "printer ready" indication on the WinXP machine, and even though the printer responded perfectly to print jobs coming from the Win7 machine.
When I tried to "fix" the WinXP setup by running HP's setup program on CD, nothing changed. Then, when I tried to reinstall the WinXP setup for wireless printing, the program insisted that I reset THE PRINTER'S factory defaults and proceed using a USB cable -- even though I wanted to simply ADD the computer for wireless communication to an existing networked printer! I would conclude that something screwed up the printer's inner settings (maybe an unsolicited and invisible HP update sent to my printer from the Internet?).
As I mentioned in my original post, I went through this process once before, reinstalled everything on all machines, and all was well. Until THE SAME non-recognition problem surfaced again!
I do not want to spend any more time on this. I went to Staples and bought a second P1102w printer (it is a nice little machine that uses a xerographic cartridge, rather than costly inkjet cartridges that frequently plug up). I'll use a USB cable for the connection, rather than the installed wireless feature, and set up the P1102w as a shared printer. I expect that all of my other computers will be able to link as a "guest" through the wireless hub and be able to print.
Thanks again.
PS. I am a retired computer-systems manager from Northrop Grumman.

IPad to wireless printer with password protected pdf files?

I have a iPad 2 connected wirelessly to a HP Photosmart 6520. I usually have no problem printing a variety of file and docs....including pdf files. My friend sent me some password protected PDF files today. I have the password and can open them just fine....but I can't get them to print. It just ignores me (no error message). Any suggestions?

FYI, in case anyone is interested, I found out what is going on.
I created the original password protected PDF using Microsoft Word. I did this because I do not have a full version of Adobe Acrobat that allows me to create files.
On a hunch, I found someone that has a full version of Acrobat, and had them create a password protected PDF file. This file worked perfectly.
Apparently, Word is not strictly adhering to PDF guidelines, and OBIEE senses the differences, resulting in the file not opening properly.
Something to keep in mind for anyone linking to password protected PDF files in OBIEE.
