HP Officejet Pro 6970 printer issue - laptop prints wirelessly but can't print from wired desktop

Posted on 2016-10-21
Last Modified: 2016-10-27
Hi, although I recently successfully set up my new HP OfficeJetPro 6970 (actually, 6978), it's now not printing (from my HP Pavilion Desktop, wired). At first it printed but now, nothing. The printer is online but when I go to print it goes offline as the print job is queued. But I can print reliably from my HP Notebook.

When the printer is idle, it's online. When I go to print, the program recognizes it as online. But it won't print, and goes offline instead of printing. A little while later, it's online.

I had connectivity issues for 2 years and with 2 different Canon printers. So now maybe it wasn't the Canon printer.

Wireless router is Verizon FIOS, and I have multiple phones and devices that connect fine, never any issues.

The configuration page says:
- Internet: Connected
- 802.11 Wireless
       - Status: Connected
       - Network Name (SSID):  FIOS-Peck
       - Signal Strength (1-5): 5
       - IPv4:  <--- this is the home network
- Wi-Fi Direct - what is this ? is this what the HP notebook is printing to ?
      - IPv4: <-- what is this ?
- Number of 802.11 networks discovered: 2
      - FIOS-Peck, WPS - No <--- Is this the problem ??? I didn't see any WPS instructions
      - FIOS-Peck_2GEXT (Wi-Fi extender upstairs) , WPS - Yes
You can read more about this here. The HP Forum said try the "Print and Scan Doctor" which I did to no avail.

so I stumbled upon the Printer Assistant, and my wired desktop PC can read the printer's settings, but it says it "is unable to establish two-way communication with this device". But my laptop is good-to-go, prints like a champ.
no two-way communication

>>  Wi-Fi Direct - what is this ? is this what the HP notebook is printing to ?  <<  this is airprint - a system ipads use to print directly to the printer
in most cases - it has very little options

probably the easiest is to uninstall the software, and run the install again
check if it uses the wired connection

In the desktop system, you have to delete any unused/extra printer and ports, specially no re-directions. Try to ping the printer IP from desktop and see if you get a response, try to open the Printer web console in any desktop browser. If all this is happening, communication is there but software connectivity may be an issue. Check if Printer IP and Desktop IP is in same sub-net. Also check which port the target printer is mapped in the desktop. Disable any power save mode in printer temporarily.

- >>  Wi-Fi Direct --> airprint - a system ipads use
- ok, I haven't tried my wife's Macbook yet
- but why does the HP notebook print like a champ ? Is it printing directly to the printer and not through the router ?
- printer is connected wireless to the lan (Verizon FIOS router)

- no response when pinging the printer IP from HP wired desktop
- I do get a response (and printer web console) from HP Notebook
- printer and PC IP are both 192.168.1.***

so the printer works via wireless (from the wireless Notebook) --> is it printing directly to the printer ?

what about this -
 - FIOS-Peck, WPS - No <--- Is this the problem ??? I didn't see any WPS instructions
 - FIOS-Peck_2GEXT (Wi-Fi extender upstairs) , WPS - Yes

I can print the configuration page from the printer and all looks well

i'm getting confused
your Q was :
"HP Officejet Pro 6970 printer issue - laptop prints wirelessly but can't print from wired desktop"

is the printer connected to the router? or to the PC
are you saying you are printing both to that printer?  one wireless and you wired?
or what? both wireless ?
anyway - the install must be faulty on the one that's not printing - or the setting in the router
also - i saw on another model that the printer asks for a WPS code - did you install that?

- printer is connected wirelessly to FIOS router
- desktop is wired to router, but can't print even though the printer has IP address, etc.
- HP notebook found the wireless printer and prints great. I did find the WPS code when trying to get the HP notebook setup, and then that worked.

When I originally set up the printer, all was  well, I was very pleased. But then it just totally stopped communication (see most recent screen shot above), even though it's "connected". So my desktop PC can see the printer, but just not print !
Printer visibleIt's always resting idly online, below. But when I print, it goes offline. Then in a minute or so, it will show online, like here:
ready to print
As I mentioned above, I had issues with 2 Canon printers. The printer works (to the HP notebook) but it doesn't work through wired PC to LAN to printer set up on wireless to router. But router works great for all kinds of devices. It has to be something with the router.

called HP Support, they remoted in to my PC and fixed it . . . :-)

best as I can tell, all they did was create a static IP address - the same as the one it was assigned - . . . it's been printing ever since . . .

Thanks for the assist anyway, I always learn things here.
