Should the display remain off while printing, then printer may be set to Sleep-Print-Sleep mode. Access the printers settings and then check the Menu Settings Pages, navigate through Settings > Timeouts > Print with Display Off. If Print with Display Off is set to “Allow printing with Display off”.
