I have a HP Officejet Pro L7780. Recently it won't allow me to print from websites, The only way I can print is to 'copy' it to a word document then print. ANy suggestions as this has only recently been an issue.

Trying running the Print Diagnostic Utility and see if it finds any errors http://http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=mp-91799-1&lc=en&dlc=en... . If that does not fix the issue try uninstalling the software and reinstalling it.

My new Officejet Pro 8500a on a Windows XP machine will not print from the Internet.

I just purchased and installed an Officejet Pro 8500a all-in-one and everything seems to work fine except that the maachine will not print from the internet. I use Windows XP home and and the Firefox browser. The printer is connected directly to the computer, and is not directly connected to the Internet or any other network.

The Officejet 8500 printers take individual ink cartridges (IIC); that machine requires that all cartridges be installed to ensure that the printhead does not get damaged. Ink is used in the printer not just for printing, but maintain the printer and the printhead. One can reduce the amount of color ink the printer uses by changing the printer settings to Grayscale or use black ink only. Page 34 of the user manual shows how one can change those settings when printing documents. For further information on how ink is used in the printer; one can look as this page here where it goes into detail on the different ways that ink is used in the printer.
I would just replace the color cartridge that the printer indicates needs replacing when the machine alerts you to low ink. I would not replace all colors at once when only one is in need of replacing.
I hope that this helps.

HP Officejet Pro L7780 Solution Center windows 7

Good Morning,
I have been trying to install the Solution center for a new windows 7computer to run a network HP Officejet Pro L7780. The CD that came with the printer is only for XP and Vista which won't install. The installation wizard downloads and unzips a file to my temp folder but no setup program launches and I don't see a file that will install the program. I also downloaded OJProL7X00_Full_14.exe fill but can't figure out how to run it.

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

OfficeJet Pro L7780 - Have to Restart Print Spooler every job I print (Windows 7 32-bit)

I have an OfficeJet Pro L7780 that shows as offline in Devices and Printers constantly. I discovered if I queue up print jobs to it and then restart the print spooler all of the jobs will come out perfectly then the printer will instantly go offline. Here is what I've done for troubleshooting already:
Upgrade to newest firmware (R2011NxNxeN0)
Factory Reset by hold # and 3 at boot
Changed Ink and Print Heads
Installed newest 14.0 driver (tried both Basic and IT Pro Driver)
Rebooted and restarted printer and computer
Tried all this on a 2nd Windows 7 computer with the same results
Anyone actually use this printer on Windows 7 32-bit over the wired network port!!?!
This question was solved.
View Solution.

Same printer, same problem, same remediation by restarting Printer Spooler service. Only difference is OS is Win 7 Ultimate 64-bit.
FYI- I'm using my L7780 via a wifi connection using WPA2 security and a static IP and network RAW printing to port 9100. The printer always appears available via network pings but not to the print spooler. As such, printer is always "grayed out" and disabled but will accept jobs into its queue.
After endless searching this is what appears to be working as a fix: Turn off SNMP on printer port.
Printer Properties -> Ports Tab -> (Select Port) -> Configure Port -> uncheck "SNMP Status Enabled"
Hopefully this works for others- but I also found mention that others found a fix in toggling other settings such as "Enable bidirection printing" check box. Who knows what seemingly unrelated software triggers this issue but it began one strange day and drove me crazy.

I have a deskjet D1420 and officejet pro L7780 neither print back to front

I have a HP deskjet D1420 and a HP Officejet Pro L7780 and neither one will print the pages from the back to the front. The option to print back to front has been selected on both printers.
i.e. printing 2 pages and the last page prints first followed by the first page
Any help in resolving this issue will be greatly appreciated. Thanks

Please read this post then provide some details. What operating system?
I do not think the D1420 has an automatic duplexer, but the L7780 should be able to be configured for this. See the Vista/Windows 7 Duplex Printing Troubleshooting Guide here.

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

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!!
Thank to ALL!

Officejet Pro L7780 printhead error

Hi,
Use the following link to perform the troubleshooting steps.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01446637&cc=us&lc=en&dlc=en&product=2512010&tmp...
If you still recieve the error message after performing the troubleshooting steps mentioned in the document, then try the printhead cleaning from the printer menu.
Setup Menu--Tools--Clean Printhead
Setup Menu--Tools--Align Printer.
If none of these help then try this reset....this reset will restore the printer to its original factory settings & will erase all settings on the printer.
Unplug the power chord from the back of the printer while the printer is still ON.
Now press and hold "# & 9" keys on the printer, and connect the power chord while holding down the 2 keys. Wait for approx. 10 seconds and then release the keys.
If the printer powers off automatically, then wait for 10secs. and then turn ON the printer using the Power button on the printer.
Hope this helps.

I have my HP OfficeJet Pro 8500 A connected to my Mac Book Pro on a Wireless network. It works and

I have my Hp Officejet Pro 8500 A connected to my MAc Book Pro which is running Lion OS on a wireless network. It works just fine and prints and everything. The problem is a "HP Utility" window that pops up on my screen and says it is "connecting to device" and lists my printer. It just runs and runs and the entire thing is gray - meaning I can't close it, cancel it, or anything. When you try to click on it, the arrow becomes the color wheel of death. It is driving me crazy. I have gone through settings, I have downloaded the latest drivers, I have looked in utilities, I have opened the printer folder and can't find where this thing is coming from or how to turn it off. Please help. And yes I have turned offf the computer and rebooted.

If you are using Snow Leopard or Lion and have HP software for pre-Snow Leopard (either from a CD not marked as compatible with 10.6 or you recently upgraded to Snow Leopard or Lion and had the HP software on your Mac before you upgraded - even if you did a standard uninstall of the old software or installed new software over the top of it) you must uninstall the software using the 'scrubber' option:
Go to Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Press and hold Control + Alt + Cmd keys on the keyboard simultaneously while you click on Uninstall <<<< This IS the Scrubber Option, there is no button labeled "Scrubber"
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
Click Continue and let it finish
Restart your Mac
Download and install this: http://support.apple.com/kb/DL907
Now 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.
If you want more features, you can download and install the Full Featured software from the "Support & Drivers" button at the top of this page, otherwise, basic printing and scanning will work without it.

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!
peace,

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.

On a HP Officejet Pro L7780 All-in-One printer, is there a toner and where is it?

On a HP Officejet Pro L7780 All-in-One printer, is there a toner and where is it located? I've looked in Products and Supplies and don't see it but my printer is saying that it's low or empty.

By now, you have probably discovered that the L7780 does not use a toner but cartridges. It actually uses 4 HP 88's. They are black, magenta, yellow and cyan. Usually, black is the first to be replaced. They can be found at Staples, Office Depot and Best Buy.
