Error code "79:04" on an HP Designjet T770 printer usually indicates a firmware error. To troubleshoot this issue, you can follow these steps:

Restart the printer: Turn off the printer and unplug the power cord from the power outlet. Wait for about 60 seconds, then plug the power cord back in and turn on the printer. This simple power cycle can sometimes resolve temporary glitches.

Update the firmware: Visit the official HP website and search for firmware updates for your specific printer model. Download the latest firmware update if available and follow the instructions provided by HP to install it. Firmware updates often address known issues and improve printer performance.
