just use cat;-)
example in perl:
@Data = ("0","0","0","0","0","0","0","0");
1 on, 0 off
if (open(INTERFACE, ">/dev/lp0")) #Wenn es geht auf das Interface
schreiben
{
print INTERFACE chr( $Data[0] + $Data[1]*2 + $Data[2]*4 + $Data[3]*8
+ $Data[4]*16 + $Data[5]*32 + $Data[6]*64 + $Data[7]*128);
close(INTERFACE);
print $Kanalnummer, $Zustand =~ 0 ? " ausgeschaltet<br>\n" : "
eingeschaltet<br>\n";
}

if you have only one LED send 0 or 1 to lp0 with echo "0" >/dev/lp0
