PC suddenly can't see network Printer

check your windows firewall. try to open the port for it. and i hope you can ping other pc's in the same network.
check your antivirus is blocking it. and check if you have any other firewall

So the PC cannot PING the printer - it just times out?

But the other PCs *can* ping the printer, at the same IP?

Have you tried resetting your router?

ckivml,

Windows Firewall turned off, no luck. I can ping all other PCs to and from each other, and the printers are all working fine for everyone except this one PC and one printer....weird.

sjklein42,

Yes it just times out. Others can ping it successfully, yes. Haven't tried the router, I'll give it a shot.

What is sufferer about this PC? Static ip? Av software? What changed recently? Find the difference and you will probably find the problem. Unless it just needs deleted and reinstalled, that just happens.

That's the problem, I deleted it to reinstall, and it has a discovery phase and it does not see the machine, then it allows for you to directly input the IP and it still can't find it. Unfortunately, it's not my PC, so I don't know if anything has changed.

With xp I always setup a network printer as a local printer, then use a tcpip port with the ip of the printer. Xp has issues with calling things network printers.

aarontomosky:

OK. This is a Sharp Printer that is a network scanner, fax, printer, etc. It needs software to installed in order to use it. You can't just go to control panel and add a printer. You must run the software, it must discover the unit and then it completes installation. I cannot ping the IP for the printer, so your suggested method will not work as the PC cannot see the printer. That is what is so puzzling about this. The PC works fine, can connect to company drives, internet, server, and all other network PCs, and the printer in question is working fine for all others on the network. It's just a problem with this one PC, printer and their communication.

It used to work - it suddenly stopped working.  Your ping test bypasses all the printer software on the PC.  It sounds like something "transient".   I know it can be disruptive, but I urge you to reset your router as soon as you can.

This looks like a bad arp cache entry to the printer. This is an L2-L3 (Mac to IP) problem if you can't ping it..

I would recommend you look at your arp cache or look for ARP cache poisoning.

Yet, another problem that would effect both ICMP echo (ping), and file/printer sharing (netbios) would be a firewall. Can you Ping Anything? Can anything ping your client PC? Can anything, except this client ping the printer?

Can you restore the PC to a date when it was working.. it seems that port is being blocked. check your AV firewall and all

you can restore your pC
1. start meny all programs > accessories >> system tools >> system restore
select the date when it was working

sjklein42:

I will try to reset the router as soon as I can. I just don't want this question to wind up labeled "abandoned"

sjklein42:

OK. I reset the router and the PC still cannot see the one network printer. It can see all the other network printers, shared drives, etc. Just the one machine can't be seen....ugh.

Sorry the router reset didn't help.

One suggestion I saw was to turn off the Firewall on the PC.  It did fix it for one person.  But not another.  But you already tried that.

Another idea is to delete the printer on the bad PC and then add it back again.  I think you tried that and you were unable to add the printer back since the PC couldn't see it.

Here's a related thread you may  not have seen:

Can't ping printer from one laptop


"I have had this exact problem twice with the same laptop. In both cases, I had to delete the printer and then do a reinstall. At least when I delete the printer, I am able to ping the IP address of the printer.
If you try reinstalling the printer using the CD installation wizard and receive an error message or unable to install, use the add printer wizard in windows and just locate the printer driver for your version of windows. This should solve this problem as it has done for me on two different occasions.
Thanks and hope this helps. "

All,

Still no luck on this one. I will try ipconfig /release and ipconfig /renew and see if that helps. Any other thoughts. Thanks to all for your help.

Deleting the ARP entry of the Printer Ports IP Address should work.
ARP -d xxx.xxx.xxx.xxx
But i always get the Same Problem after every Standby and have no Solution for that.

The PC has been replaced. The issue was never resolved.
