Officejet Pro L7780 locks up when connected wirelessly

I'm trying to set up my iPad to print to an Officejet Pro L7780. Prior to beginning this effort, we were able to print to this computer through an ethernet connection no problems.
However the printer won't function once it connects wirelessly - locks up entirely. Can't get iPad, PC w/Vista, or a PC with XP to recognize the printer on the wi-fi network. And, printer button functionality is gone, including the power button. Any suggestions?

Hello gathey,
You can click the links below for two documents dealing with wireless network issues for your printer.

I will remind you that your printer can be hardwired to your network and the iOS device be wireless, as long as it is the same network.
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!

WRT54G router locks up when connecting wirelessly to a Samsung Blue Player

My WRT54G router locks up 100% of the time when attempting to connect connect wirelessly to a Samsung Blue Player (Model number BD-P3600). I can connect to it with a cable no problem, but when I attempt to do so wirelessly and type in the password on the Blue Ray player, it attempts to connect but the router locks up and all devices connected to it (wired or wirless) lose connectivity. Any ideas?

Try the following steps:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page.
# Then Click on wireless Tab select Channel Width to 20 MHz only and Channel to 6, 9, and 11. Click Save Settings.
#Adjust the following advanced wireless settings:
~~ Lower the beacon interval from 100 to 50
~~ Lower the fragmentation threshold from 2346 to 2306
~~ Lower the RTS threshold from 2347 to 2304
Then check the connectivity status..

Officejet pro L7780 printer freezes after new wireless router wpa2 code is entered.

I recently changed routers and attempted to add the new WPA2 code. Using the wireless setup wizard on the printer it allowed me to get to the very end where the printer says network installed press OK to continue. Unfortunately pressing OK did nothing and all keys/buttons on the control panel do not respond. Tried removing the software, resetting the control panel by holding 6 & # during power off/on no help. Running windows 7 bit.

It could be that the printer does not support WPA2. Try WPA.

HP Officejet Pro L7780 - Network Letter Nightmare!

Hello.
I'm hopin somebody can help with a problem I am having with my HP Officejet Pro L7780:
The printer is connected to my wireless network and all is well with this. The problem lies with the network letter that it assigns itself to on my PC (Windows 7 Ultimate) for the in-built card reader on the printer. It is using the same letter as a virtual cd-rom drive on my PC - and I would like to move the letter the printer uses - and not the cd-rom drive, as I have my PC setup in a way where different types of drives are grouped together. Is there some way (possibly through the Windows registry) that would allow me to change the letter of the network drive (as it seems to automatically assgn one) and keep it using that new letter rather than interfering with the cd-rom drive and denying access to it every time Windows 7 boots?
Or alternatively disabling the card reader function on the printer as I don't use it?
Thanks to anybody who can solve this - as it is driving me mad!
This question was solved.
View Solution.

I finally found a solution to this problem that works for me.
I too have an HP printer that was mapping its memory card slots to a Z: drive every time I booted my Windows 7 computer.
To change the mapping to another letter to free up the Z: letter, I placed a memory card into one of the printer memory card slots. I then disconnected the Z: drive from the printer mapping (right click the Z: drive in Windows Explorer and choose the Disconnect option).
I then used the "Map network drive " option on Windows Explorer toolbar to map the printer memory card slot to another drive letter. You have to know the network address (or name) for the printer to do this: \\[printer network address or name]\memory_card (e.g.: \\192.168.1.108\memory_card). This address goes in the "Folder" textbox of the Map dialog window. Make sure the "Reconnect at logon" option is checked. And make sure you select a new drive letter that won't be needed for anything else later. Then click "Finish."
After I did this, the printer has continued to use the new drive letter at boot-up instead of Z:, leaving Z: free for other applications.
I don't think the above works if there is no memory card in one of the printer memory card slot.

Can't configure Wireless Connection to HP OfficeJet Pro L7780

I recently purchased both my iMac 24" 2.8GHz computer with OS x 10.5.2 and HP OfficeJet Pro L7780. I was able to use the HP setup CDs for my Windows laptops and configured them to use the printer in a wireless configuration.
The iMac is creating the headache (actually I think it's HP causing the headache). When I try to install HP's driver 9.7.1 using their utility, it is unable to detect the L7780 in a wireless configuration. The moment I connect via USB or wired Ethernet, the printer is detected without a problem. My printer is located @ 192.168.1.30, fixed IP address via a NetGear FSW308 switch. My iMac is fixed @ 192.168.1.100 and the gateway is 192.168.1.1
I spent hours on the phone with HP support and am still in the same spot... HP software won't find the printer when it is wireless. I can configure OS x 10.5.2 to use the internal L7700 series driver and put the IP address in the dialog box. The printer prints without issue using the OS printer drivers, but the other features such as scan and fax will not work without the HP software.
I can ping the printer and I can connect to the printer's EWS, but the HP software will not find the software.
Overall config: iMac wireless network connection to switch; Printer also wireless connection to switch.
So far HP is dumbfounded and all they can say is that I should call Apple because the printer software works fine when I connect the Ethernet or USB cables.
HELP!
Thanks,
Roland

Thank you for the thought. Yes, although my SSID is public, I have a WEP 128-bit security key. The printer, the iMac and my Windows laptops all connect to the wireless network without issue, as evidenced by my Windows laptops and iMac (if I use the driver included with OS X 10.5.2).
I can ping the printer from the iMac as well as connect to the printer's web interface, so connectivity exists. It is as if the setup software or the printer are trying to communicate using a port that or service that OS X may be blocking.
My OS X firewall is configured to accept all connections though... so that shouldn't be the issue unless there is a bug in accepting all connections.
Thanks,
Roland

Officejet Pro L7780 Wired and wireless networking at same time

I have an officejet pro L7780 printer that I would like to use wired and wireless networking at the same time. It that possible. The printer is connected directly to the network by ethernet, but I would like to print wirelessly with an ipad or iphone using HP ePrint Home and Biz.
Thanks,
Maurice Hawley

The bad news: no it is not possible to have two connections active on your printer at once.
The good news: the router will connect any device to the printer regardless of how the printer or the devices are connected. So your iPad can print to a printer that is wired (with Ethernet) to your router.
If it does not work, restart your router by pulling its power plug momentarily.

2nd iPod Classic locking up when connecting to MacBook Pro

I'll sum up the lead-in story as best I can.
I have a 2010 MacBook Pro 13". Just got an new iPod Classic a couple weeks back. I discovered that when playing the iQuiz game, I had a few lock-ups (freezing). Then a handful of times, it locked up when connecting it to the MacBook for charging or syncing. It didn't lock up EVERY time. But about 1 out of every 4 syncs on average.
I naturally thought something was wrong with the Classic, and brought it into the Apple store when it was locked up, and they gave me a new one.
But now this one is doing the same thing. Occasional lock-ups when connecting to the MacBook Pro. Doesn't matter which USB port. And doesn't seem to matter if the computer has been on, or if it's a fresh boot.
What could be going on here? I doubt highly that both Classics I've gotten have the same exact issue with occasional lock-ups when connected to the computer. My MBP otherwise has given me no problems. And no problems with other USB devices, ever.
Any ideas?

Update: bought a new usb sync cable to try, and no change. the Classic locked up the first try with the new cable.

HP Officejet Pro L7780 All-In-One printer

I am running Windows 8.1
The printer status OFFLINE.
It has done this in the past and I have been able to correct it by deleting and reinstalling it (at least back when I was running Windows XP and 7. Possibly at that time it was the DHCP issue pointed out in a previous post.
Now however, I can remove it and when I add it back, using Control Panel, Devices and Printers, Add a Printer, it is recognized correctly on the network (shows the IP address I know is in the printer) but when I try to send a test page, I get a pop-up saying it is OFFLINE. When I status it, it confirms it is offline.
There is no indication at the printers display that it is offline and it shows it is communicating with the network.

Appears to be a hardware problem, any ideas.

Hello Minabird4
Welcome to the HP Forums, I hope you enjoy your experience!
I understand that your wireless radio is not working on your HP Officejet 8500. This could be a hardware issue if the wireless card has failed completely, but I would like you to try the HP Support document: Performing a Partial Reset of the All-in-One. If resetting the printer as the document gets you to do does not fix the issue, it would be recommended that you contacted HP technical support for repair options.

HP Officejet Pro L7780 All-in-one not scanning with Yosemite

I have searched for a workaround or fix to the scanning problem I'm having. I just bought a brand new Macbook Pro Retina and have loaded the latest printer drivers for the HP Officejet Pro L7780. The printer works ok, but I can't get the scanner to work. When I try, it says: "Failed to open a session on the device."
I'm using the printer over a wifi connection.
Can anyone help with this, please?!
Thanks!

HP Officejet Pro L7780 won't print individual pages of a file

I have a HP Officejet Pro L7780 setup with wireless printing on my network and am using Windows 7 on a 64-bit computer with MSWord 2007. I'm trying to duplex print just specific corrected pages (like pages 7-8) from a file (of pages 1-22) and my printer just won't do it. When I select to print specific pages, the printer just sits there and then the print queue is apparently dumped, as the tray icon just disappears. The printer will print only all pages of a file or nothing at all. What could be the reason for this and how do I correct it? Thanks, Patricia

Why can't I fax from My HP Officejet Pro L7780 ? ?

I recently updated to Mavericks and for some reason I can't send a fax through my "HP Officejet Pro L7780 All-in One."
I used to be able to send faxes from "Word" or other Apps
When I look at the configuration: "System Preferences" -> "Printer & Scanners" I can add the printer only but I can't add the fax.
I have checked for software updates and have found none.
Some one please help.
Thanks

This problem has been solved in OS X update to 10.9.3!!
