Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The "79 Service Error" on HP printers usually indicates a firmware issue or a problem with the print job queue. Here are some steps you can take to troubleshoot and resolve this error:
1. Power Cycle the Printer:
- Turn off the printer, unplug it from the power source, and wait for about a minute. Plug it back in and turn it on. This can sometimes clear temporary errors.
2. Check for Pending Jobs:
- On your computer, go to Devices and Printers, right-click your printer, and select See what’s printing. Cancel any pending print jobs.
3. Update Firmware:
- Ensure your printer has the latest firmware. You can check for updates through the HP Smart app or the HP Support website. Updating the firmware may resolve the error.
4. Reset Printing System (on Mac):
- If you're using a Mac, you can reset the printing system:
- Go to System Preferences > Printers & Scanners. Right-click (or Ctrl-click) in the printer list and select Reset printing system. Then, re-add your printer.
5. Uninstall and Reinstall Drivers:
- Completely uninstall the printer drivers:
- Go to Control Panel > Devices and Printers, right-click your printer, and select Remove Device.
- Then, visit the HP Support website to download and install the latest drivers.
6. Check Network Connection:
- If you’re using a networked printer, ensure it is connected to the network properly. Check the printer’s network settings and reconnect if necessary.
7. Check for Software Conflicts:
- Sometimes third-party software or firewalls can interfere with printing. Temporarily disable any security software and try printing again.
8. Factory Reset:
- If all else fails, consider performing a factory reset on your printer. Refer to your printer’s user manual for specific instructions on how to do this.
I hope this helps.
Take care and have a good day.
