HP DesignJet 0079-0000 Error
For the DesignJet T730/T830 family, HP directs a restart for 0079-0000 and recommends a firmware update if the same error returns.
What this code means
This is a firmware/system error rather than a paper-size or network-address problem. The safe published path is restart first, then check current HP firmware if the error is persistent.

What to try
Restart the printer normally.
Let the machine complete its startup before deciding whether the error is persistent.
If it returns, check the installed firmware.
Use HP support resources for the exact T730 or T830 model.
Install current HP firmware when available.
Use only firmware intended for the exact model and keep the printer on stable power throughout the update.
Retest after the update.
Once the printer is fully ready, send a small test job before retrying the original workload.
When to stop and get help
If 0079-0000 persists on current firmware, contact HP support/service with the full code and firmware version. Do not install firmware from a different DesignJet family.
