Hi, I've had a very similar issue with Parallel printer Samsung ML-4500. Sending the data to the printer activated the printer for about 10 seconds with light blinking. Nothing came out in the end. I've resolved this issue by changing the parallel mode in the bios either to ECP or EPP, I don't remember now and don't want to reboot my PC to find out. Try changing the bios settings and see if it will work.
