  • 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

  • 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.

  • Thank you for sharing the instructions. It worked after restarting all the devices but the 79 service error keeps coming back after few days.

  • Maria Wilson says:

    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.
