Q: Unable to verify the printer on the network

Hi,

 

I have a home IP network with an HP4100N network laser-printer connected via JetDirect card to a powerline device and then to a hub.

Up until recently, all computers on my network could successfully print to the printer via the JetDirect card and IP (192.168.0.100).

 

HOWEVER, my girlfriends MacBook Pro running Mac OX 10.9.5 suddenly stopped printing to the printer and things were just starting to build up in the print queue. The printer continues to print normally for everyone else on Mac and even a Windows 7 machine, eeek!

 

Turning the printer on and off a couple of times, resetting the network etc, I then finally deleted the print queue and tried to setup a new connection to the printer again on her computer via the prefs and the IP JetDirect socket option (like I have done on all the other computers).

 

When I enter the printer IP address into the Mac Printer & Scanners settings, Mac OS tried to interrogate printer model etc and it comes back with a Generic Postscript Printer profile and not the HP specific one. (Again, every other computer can setup fine at this point!)

On her computer, when you try and install the printer with the wrong profile (or even the correct one if manually chosen), it eventually says:

'Unable to verify the printer on your network'.

 

Network utility:

I then tried using the Network Utility to ping the printer from my laptop, this works.

I tried to ping the printer from her computer, this doesn't work and it times out!

then...

I tried pinging her MBP from my MBP and this works. Then I pinged my MBP from her MBP, this works.

 

So her computer is on the network, but is not able to see the printer.

I then hard- IP'd a new IP address on the printer (just to rule this out), setup all the computers to this new printer, all worked well except for her computer, which once again couldn't see the printer. (I can't ping to it either again from her computer, even with the new IP!)

 

I think I've tried all the obvious things, updating software, resetting things, turning the firewall off completely....but all to no avail.

The problem, it seems to me, is with her MBP rather than with the network or the printer (as all other computers can print!).

 

So...the million dollar question is... Can anyone tell me what is going on?! How do I get her computer to print to this printer again??

 

thanks very much.

MacBook Pro (15-inch Mid 2010), OS X Mavericks (10.9.5)

    Dumb questions, but is her MBP set to DHCP?  And have you shut it down completely and restarted it?

    nostrawaggus,

     

    I had this same error with only one of our many iMacs when dealing with a Sharp MX-M753n (not an HP printer). Everyone else, PCs and Macs, were working just fine, but when setting up the iMac that I'm talking about, I was baffled. I deleted printer queues, deleted/reinstalled drivers. None of that helped.

     

    For kicks I changed the protocol being used from IPP to HP JetDirect and it fired up.


    I've attached a couple of screenshots detailing the setup that failed and worked:

    I hope this somehow works for you.

    This kind of makes sense - IPP is only found on printers made/designed after ~2000. So, good recommendation.

     

    If you still have trouble - it seems something in the OS X is corrupted. I'd try a Safe Boot, then reboot back to normal:

    yup, her (and all the other home network computers) obtain an IP address via DHCP lease. I could try deleting her lease on the router, but as I mentioned, everything has been restarted so this should have done that job via those means.

     

    The printer is the only node (apart from the router GW) which has a hard coded IP address.

    Hi Jay, thanks for your help on this. I will try your suggestion tonight at home. Thanks.

     

    It is really baffling me, especially since on a very basic Ping networking level, the printer doesn't

    respond to her MBP. It's almost as if the IP is being filtered somewhere, which made me switch her firewall off completely for testing.

    This didn't help. There's no other software that I can think of that might be interfering. She does have some other printers installed on there for when she's in the office (Brother, Canon) - will have to ask her to see if she can print to any of those or if they have the same issue - but they don't use JetDirect etc and the printers shouldn't be interfering with each other anyhoo?!

     

    The problem has been ongoing for a while now, started on 10.9.4 and now is also on 10.9.5 so the Mac OS update hasn't resolved anything. The new Apple HP printer driver package has been installed too during my attempts. It is most annoying and weird.

    Upon fiddling around the other night, the Mac was able to see the printer again and I was able to set the printer up using the normal JetDirect Socket. I haven't changed anything on the Mac or on the network to enable it to work, it just worked by itself...until....

    today...she tried to print again and we have the same problem as before. The print queue that worked for the last 4-5 days, now queues all the documents sent to print, and the Ping to the printer from her MBP reports no route to host again (the IP is definitely on the network as my computer can ping to it).

    This is really weird. I have no clue what is going on. I'll try the Safe Boot next....

    Sounds like the router doesn't respond to requests from the printer, or vice versa.

    To see if I'm right, you need to go into your router's setup web page and set a reserved local IP address for the printer. That way, the router will know to always give the same IP address to the printer. (This is advisable for any "server" on your LAN, including computers that you often share files from.)

    Yeah, I would agree with you completely Greg, but the baffling thing is it just affects this one Mac. How come it routes 'selectively' so to speak? It works for everyone (incl. Windows 7 machine) but not for my GF's MBP... until such a time that it suddenly feels like working again (all by itself by the looks of things).

     

    You are right in saying that it defo appears to be some kind of routing problem, but I'm having difficulty in finding out where the problem actually is. Is it the router, the printer or her computer? Could it be the firewall on the router blocking it for her and not for others for some reason? If it was the router, you would expect it to tarnish everyone with the same brush, would you not?

     

    Whilst the HP printer has the static IP manually set up on that side (192.168.0.100), the router hasn't specifically been told that the printer has the .0.100 address hard coded into it I don't think, so there is a possibility for it to be going weird here. I'll need to look at the router config page tonight and just lock that 0.100 address to the MAC HW of the printer. Perhaps that will do the trick, but still wouldn't explain why it's doing it selectively just to that one computer (not even randomly to others on the network).

     

    I did try the safe boot too. Within that I ran Disk Utility to fix some file permission errors (there were some group permission problems for the new HP software that I had installed on her computer actually, which DU had fixed). Whilst running the utility, it did throw back issues about the EFI partition map being corrupted etc, but that seems to be a separate problem with the disk utility software not being able to run/fix from the disk it is being booted from, even in safe mode. But this is being discussed elsewhere on Apple Forums and I don't think it's connected to the IP problem I'm having.

    Whilst I was doing the Safe Boot thing, I got sidetracked (isn't that always the case when you troubleshoot) and didn't try and set the printer up within that environment, but instead was trying to figure out why I was getting the EFI partition Map errors. It turned into a late night and I had to hit the sack at some point...

     

    I tried IPP too. Putting the Printers IP into the address field on her computer didn't result in the HP Printer profile being selected when it tried to find the printer, this stayed as Generic PostScript. I didn't explore any further on that occasion to see if I could manually set it all up and print to it or if the set-up would just hang again. I figured if the IP address of the printer isn't visible to the computer (ie. no route to host), then changing to IPP wouldn't work either.

     

    I'll give these options another go tonight when I get my hands on her computer again.

    Jay,

    I've been trying for a week now to get my networked printer (Canon)to work.  I stumbled upon your post.  All I can say is you are a genius!!!!  Thank you so much. I followed you post and it worked.

    Thanks Jay and Greg. I could print normally using USB but my wireless capabilities stopped.  I just had the same problem with my HP C410 series printer.  After many attempts at deleting/re-adding the printer software, printer, etc to no avail; I did a soft boot and was able to re-add the printer successfully via the normal Mac Windows and using the actual HP C410 data.  Will now have to try the same thing with my wife's Macbook which is doing the same thing.

    Hi,

    By resetting things, have you also restart your router? if not please give it a chance by unplugging its power for few seconds.

     

    Beside the internal OS X firewall, may you have any 3rd party security software installed? e.g. Norton, Eset, etc.?

    Hi, yes I always do a full reset. Router, printer, everything.

    For the moment it's working again. Not quite sure what I've done, but I'm keeping my fingers crossed.
