Problem/Answer
This error occurs when the printer receives a corrupted or unsupported data command. The "buffer dump" means the printer has discarded the current data in the input buffer due to an error in the data format.
Possible Causes:
- Incorrect printer command language
- Damaged or incomplete data sent from the host device
- Driver mismatch or outdated firmware
- Interface communication issue (USB, network, etc.)
What to Check:
- Verify that the correct printer driver is installed.
- Check the data being sent matches the printer's command language
- Make sure the printer is not receiving garbled or binary data by mistake.
- Restart both the printer and the sending device.
- If using custom software, check the print commands for syntax errors.
