  1. I did a similar but performed the steps in a different way for my hp 79 service error as you have mentioned it could be due to a miscommunication due to the printer/network. i switched off my printer and the router and without switching on the router i turned on the printer first to see if the error code 79 service error remains or not. After that, i restarted my router and the error was gone.

  2. Thank you for sharing the instructions. It worked after restarting all the devices but the 79 service error keeps coming back after few days. I have to restart everything back again when the error message pops back up. Is there something i am doing wrong with my printer or is this the hp printer fault?

  3. I have three hp laserjet pro 400 for my small business shop and this 79 service error always pops up after ink change. These printers are just about a year old and i just want to throw them away. Tired of HP products as well as the hp customer service. Connection failure or printer stops working after automatic updates, the problem list goes on and on. They are just good at making the crappy products. I am changing all my printers to epson, the two epson printers that i have in my office never gave me any problems and gives me no headache unlike HP.

  4. I still have the 79 service error on my HP printer. Did anyone else try any other steps that resolved this issue. Any help would be great

  5. The first step help out for my hp printer 79 service error but i tried a little different way. did it by removing all the other printers that are listed on my computer and switched off the router, the printer and my computer for more than 5 minutes and the error was gone

  6. Switch off the printer, remove all the cables connected to the printer, press the power button for few seconds and reconnect the cables and power up the the printer and 79 service error will be gone. Thats how i fixed the error message on my hp printer.

  7. It did not work for me. I have tried everything available on the internet for 79 service error and none of them provided anything that could solve this problem, this printer is old and has no warranty, so i got no support from the hp technical support. now i have to take it to a local printer shop to get it serviced.

  8. Hp is really doing a great job. They manufacture printer that is filled with errors (like 79 service error i have) which has no fix so that they can drain more money from us for fixing it. I paid a lot for this printer and their ink cartridges are very expensive and now i have to pay almost the half amount of what i paid for the printer to get it fix. Well played HP, never going to purchase any hp product from here on

  9. It is not working for my hp 79 service error. I have even remove all the cables from the printer and pressed the power button for more than a minute but it is still the same. Stuck with the error

  10. Yup restarting the router resolved the hp 79 service error. I have tried cycle on and off and updated the firmware but nothing worked. Thanks

  11. None of the steps worked for my hp 79 service error. I took the printer to a local printer repair store and got it serviced. It is very expensive to repair hp printers, just as high as their ink price
