Connect the GND directly to GND and not through the spindle relay connection.
For the TTL - either choose an LPT Output pin that is not used by your stepper motors (for M10P1 / M11P1 control of the laser) or the Z axis Direction pin if you are taking that route.
If your pin 4 is Z axis Direction then Mach3 will set this pin high or low depending on your GCode Z axis +/- moves. In turn the laser beam will be switched on or off.
