Check your parallel cable. unfort. my printer is connected properly and it is on while simply trying to open it with open(/dev/lpt0) - lptest > /dev/lpt0 fails too ... so it seems that fbsd expects some kind of status reply from the printer - correct? if so: how could i by-pass this? (cause my ugly gdi printer is probably not able to answer correctly) i just wonna have access to my parallel port ... thx regards, stan
