I skipped following steps 1) # ./MAKEDEV port and 2) # lptcontrol -i -d /dev/lpt0 (to set interrupt-driven mode for lpt0) and 3) # lptcontrol -p -d /dev/lpt0 (to set polled-mode for lptN) Jumped to; # lptest > /dev/lpt0 only strange symbols printed and printing continued without stop until I removed the paper tray. Communication between printer and port seemed working Kindly advise how to fix the test printing error. TIA B.R. Stephen
