How do I change the printer's baud rate?
You can adjust baud rate, parity, and other serial settings via the DIP switches located inside the paper compartment or by sending configuration commands.
Why is the printer not printing?
Check if the power is on, the paper is loaded correctly, the interface cable is connected, and the printer is not in error state (e.g., cover open, paper jam). Try printing a self-test by holding the feed button while powering on.

How do I perform a printer self-test?
Hold the FEED button while turning on the power. Release the button after the printer starts printing the self-test page. This prints configuration and print quality information.
What is the power consumption of the printer?
The printer uses a 24 VDC, 2.5 A external power supply. Typical consumption is about 60 W during printing and much lower in standby.
