I own a HP Photosmart C5180 printer and sometimes, the LAN connection between the printer and my computer running Windows 7 is broken… even if the printer is switched on and “pingable” on the LAN.
Restarting the computer and/or switching off the printer fixes the issue but this is really a pain to do that all the time!
This boring situation is caused by the HPSLPSVC service, also known as the HP Network Devices Support service. To fix that :
- Power off the printer.
- Open a Command Prompt with elevated privileges.
- Input the following command: net stop HPSLPSVC.
- Power on the printer.
- Input the following command: net start HPSLPSVC.
Now, check the HP Solution Center. Your printer should be available again!
