  If the printer on your Tuttnauer Laboratory Equipment isn't printing, consider these steps: 1. Make sure paper is properly inserted into the printer. 2. Turn the machine off, then back on while pressing the feed button on the printer. If a test printout appears, the printer itself is working, and the issue lies with the electronics. If no test printout appears, there's a problem with the printer.
