C4788-goes offline during printing. event codes 69666, 69556

Hi,
My printing (HP photosmart c4788) was working all fine till recently. But now it goes offline while printing one or two pages.
Have done the following:
- Re-configured printer wireless networking, static IP
- Took the printer near the router
- tried from another computer
- Enabled port 9100 on my router
and all has failed.
Lastly it works fine with USB cable.
Please help

and oh my god.. the problem is there when using UBS cable as well!

Lap top keeps going offline with printer

I have an HP Envy 17t Quad touchsmart laptop and an HP 4635 printer, both of which were purchased March 2014. Never problems with wifi connections until the last couple weeks. The first time all the computers on our network were not communicating, so we reset the router and got them back up working.
But now am having an almost daily issue with the lap top going offline. The desktop is fine, but I have to restart both the printer and the laptop to get printing again.
At first I thought we might have router issues, but now am wondering if there is a problem with my new laptop?
Please advise

Hi @Odeb Happy Friday!
From your description, the first thing I think of is the possibility of the printer having a manual/static IP. If the Printer has a static IP ad that IP so happens to be the same as what the computer has, maybe turning the printer on is kicking the computer off of the network. I am not sure how doing a system restore would be resolved this, even temporarily, but let's try a different approach and see what happens.
First on the printer I will have you restore your network defaults, then run the wireless setup wizard to reconnect your printer to your network. To do this, arrow down to Settings and press OK, navigate to Wireless and press OK, then look for Restore Network Defaults and press OK. Once the defaults have been restored, look for and select Wireless Setup Wizard in the Wireless menu to run the wizard.
Now restart both the computer and the printer and see if you can maintain a wireless connection on the computer. Please let me know if this resolves the issue. If the issue persists, we will have eliminated this possible cause and move on to the next.

Printer goes offline after printing

Hello, I have an HP Laserjet Pro MFP M476DW used wireless, which worked fine until the upgrade to Yosemite 10.10.2. Now go offline after you have printed a copy and must be turned off and on for printing. And then press the last thing in the print queue and then goes back online. I uninstalled / reinstalled updated drivers etc but the problem persists. Can anyone advise please?
Thank you, Emanuele.

If you haven't done so already, try resetting the printing system.

Virtual SBS2011 goes offline during backup

Hello Everybody
We have a virtual SBS2011 on a 2012 R2 host.
Everytime the backup runs it takes the SBS2011 offline so disconnects everybodies Outlook and folder re-directions.
Other VM's are all OK it's just the SBS2011. When I try to upgrade the Host components it just says they are up to date and doesn't give me the option to upgrade or repair.
Help please?
Thanks
Daren

What state does the VM go into during the backup? Saved?

HP LaserJet 600 M602 printer goes offline every night

Hi,
I have a HP LaserJet 600 M602 CE991A printer on a wired network. I have quite a few other printers on the network as well and do not show me this kind of behavior.
But for some reason, this printer, from as soon as I bought it, goes offline every time from around 5.20-5.30pm to around 8.30pm. I have a ping tester running as I am trying to figure out what's going on and I got 100% drop every night for that time period.
I looked to see if there was a setting that puts this device to sleep or so but no, I cant find anything. I have tried with the energy setting sleep mode on or off, wake up events to trigger a wake up call to the printer but no luck.
Firmware Bundle Version3.2.5
Firmware Revision2302908_435019
Firmware Date Code20140529
I am out of options, in our other locations, we have sam printer but a CE993A models and they do not show this kind of behavior at all.
I am at a deadlock here.

Hi @Halan ,
I see by your post that you aren't able to print when the laptop isn't in the same area as the printer. I would like to help you out today.
What is the distance of the printer and the Laptop when the printer goes offline?

How do I find out what the EVENT CODES in the Printer Log mean?

My C310A has some event codes in it Web page under TOOLS, EVENT LOG.
Some it seems just indicate I printed out some reports. Others appear to be NETWORK RELATED?\
I have 69552, 74739, 74740, 74741, 74899 and 75900 showing.
Can anyone point to a URL to see what they mean or decode these for me?
Thanks,
Irv S.

What a useless support system they have constructed here. Why have Event Codes if there is no database of definitions? Why construct a forum if you're not going to adequately staff and respond to customers' questions?

Try creating a new user with admin rights, log into that new account and reinstall the software and try printing from that account.

HP LaserJet Pro P1606dn Printer constantly goes offline

We have a HP LaserJet Pro P1606dn Printer. We initally put this on our print server. But almost immediately it goes offline. Current settings:
Jam Recovery: Auto Auto Continue: On IO Timeout: 1800 Auto Off: Disabled
Since it was so problematic - we took it off the printer server and are allowing access via IP (not going through our prit server) and it is behaving the same way.
Has anyone else seen this? Any suggestions?

HP Photosmart B110a constantly goes offline and won't print via USB either

Macbook Pro OSX 10.6.8
HP Photosmart B110
I've connected the printer to my wireless network without any issues, but when I first tried to connect my macbook pro to the printer, it would keep disappearing from the network. Once I finally managed to connect it, every time I go to print something now, it will always say it is offline. Even when I try and bypass the wireless connection and connect via USB, it will still say it is offline.
I've have tried reinstalling the printer and driver many times, and I've tried connecting 2 other macbooks via the wireless and all experience the same issue. It is starting to get incredibly frustrating having to reinstall the printer over and over again.
I would appreciate a solution that would prevent it from always going offline, even If I have to give up the wireless 'feature' and permanently print via USB. I do not have time to continuously fiddle with the settings every single time I need to print a document.

Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway.
- Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

SOLUTION to your HP printer going offline and/or constantly disconnecting from the network

If you are having a problem printing, scanning or faxing with any HP Printer because of it going offline and constantly disconnecting from the network, here is the fix!
I figured this all out after many unsuccessful attempts with HP Support, my Internet Service Provider and various troubleshooting tasks including reinstalling HP software over and over and over. Well, through self teaching on the internet and 6 grueling months of research, I FINALLY figured it out. OMG! I am a Paramedic (not IT) and somewhat computer literate but by far no expert. I here all of you! Nobody seems to have the answer but I am 97% sure that I do. Either way, please reply back and let me know that this did in fact work for you! :-)
It doesn't matter if your printer is installed wirelessly or wired. Don’t worry about reinstalling your software, no recycling your printers’ power or your Router/Modem. The reason your printer is unstable on the network and continues to either go offline or disconnect from the network is NOT because the software is glitched, it’s not a firewall problem per say, it’s not a router problem, there isn’t a problem with your power cord, it’s because most networks use a “range” of IP addresses and for security purposes, it sort of “cycles” the various devices’ IP addresses to decrease the chance of an attack. A printer is no threat but the “network” doesn’t possess human intelligence so it doesn’t know this. Below are my step by step instructions on how to basically make your printer hold its IP address (static IP) instead of changing back and forth through a cycle therefore dropping your printer off the network or disconnecting.
Funny, if you are someone who has had items in your print cue, they won’t print, and you turn your printer off and then back on and suddenly your documents print…well, join my club. The reason this works is because when you first turn on the printer, it starts with the same IP address before it cycles. If you are someone who sits there for a while and suddenly your documents print without you changing anything…this is because through the IP cycle change, it hits your printers IP address and the network will allow it to print. Not very funny, I know. It took me forever to figure out why my printer would print sometimes but not all the time. Since I figured this out, I can SCAN, PRINT and use all of the features of my installed HP software such as HP Solution Center, Photosmart Essentials.
On your printer, go to menu/setup/network and press OK. Inside the network menu, print a "network configuration page" so you can see the IP address and other settings for your printer.
Now, go back to main menu on your printers’ screen. Or you can go to your web browser and type in the IP address using the decimals too and this will take you to your printers’ web page. Choose: setup\network and press OK. Look for IP settings and press OK. Choose "manual" instead of "automatic". Enter the IP address there manually as well as the default gateway which you can see on the network configuration page that you printed earlier. Note: If you manually set the printer's IP, make sure that it is outside of your router's DHCP range. Otherwise you may run into an issue with duplicate IP's on your network. (If you don’t know how to do this, write back and I will explain). Don’t forget to click “save changes”. Now, restart your computer and print anything you want. :-)
A trick I often use with printers in DHCP networks:
In Printers and Faxes right click on the printer and select “properties”. Click add a new port. Choose standard TCP/IP port configured to the printer host name. Read the hostname from the printer's network configuration sheet.
Using my method means that you always connect to the printer even if its IP changes (which may happen with dynamic configuration). This does not jeopardize your network security. It just tells your printer to stay put and stop traveling the IP address highway. :-)
This question was solved.
View Solution.

The DHCP range is the range of IP addresses the router hands out automatically as devices join the network. The DHCP range is determined by the router and each brand has a range set at the factory (that can be changed by you).
Your D-link's DHCP default range is 192.168.0.100 to 192.168.0.199. So, outside the DHCP range is .2 to .99 and .200 to .254.
Attached is a handy cheat sheet.
You can change this range by entering the router's settings page - type the router's IP address into a browser, enter the login info and navigate to the DHCP settings area (varies based on router, hunt around).

HP D110 Printer Keeps Going Offline

My HP D110 keeps going offline and this is driving me crazy. You would think that there would be a clear solution to this by now, but there is not. Please DO NOT post an answer unless YOU KNOW it will work. I have been through hundreds, maybe thousands of solutions, and none of them work. The problem is not my computer because I have no issues with any of my other devices. None of the computers at my home can stay connected to this printer, so all of the computers are not faulty. I connect with my wireless router. Yes, I have a strong connection. Yes, it SOMETIMES works by restarting the computer but I should not have to do this every time!!!! Yes, I have went to the devices page and checked "print offline". I am so sick and tired of this advice because it DOES NOT work! The only solution: Completely uninstall the entire software package and reinstall it. This takes a long time and I am sick and tired of doing this every time I want to print off one email. Does anyone have a solution?

Hello ,

HP OfficeJet 6500A Printer goes offline shortly after setup

Hi,
Question is: How do I stop my HP 6500A e710a-f printer from going offline? (this is NOT the 6500A+)
I have a Dell laptop running Win8.0, connecting wirelessly via a Huawei B593 LTE router. Printer is HP 6500A using the E710a-f driver. Printer is attached to the router via an ethernet cable.
I can create a new HP 6500A printer and print a test page over the wireless network. However, shortly after this, the printer goes 'offline'. I have tried to re-connect by restarting the Printer Servies, but - again - this only helps for a short period of time. i have also re-created the printer from scratch by deleting and then re-creating the printer. Again, the same result.
This should be a standard offering for what is an expensive home office printer with standard ethernet ports. Most home offices use wireless routers - so this should be a simple connection.
I have looked through the Forums, but not seen any definitive answer - a lot of suggestions over the last few years, but no straight answer. Apart from the guy who left and bought an Epson instead........!
It cannot be that hard to fix what should be a standard offering for this printer.
Can someone help me?

Hi @MagnusB
It might be best to start with the basic ( I know you have probably done mot if not all already, but bear with me here). The following document well guide you through the necessary steps to begin.
