Printronix: Darkness

If using wax ribbon, we recommend your darkness is set between 0 and 5.

If using resin ribbon, we recommend your darkness is set between 10 and 15.

Press the green Pause button on your printer to open the main menu.

Use the physical navigation keys to navigate to Settings > Media > Image > Print Intensity

Press the Enter key, and use the Up and Down arrow keys to adjust the value.

If you see the ENTER SWITCH LOCKED message, just press the Up and Down arrow keys at the same time, and you should then see ENTER SWITCH UNLOCKED.

Press Enter again to apply your settings, then unpause the printer and choose Save Permanently in Active Config.

Keep in mind that print quality/darkness is also affected by the Print Speed. The slower the Print Speed, the less energy is needed to transfer the ink; so the Print Intensity should also be lowered accordingly.
