First you have to change the labview.ini file and add the line:
serialDevices="COM1;COM2;COM3;COM4;COM5;COM6;
COM7;COM8;COM9;LPT1;LPT2;LPT3;LPT4;"
Then you can use the LabVIEW Serial Port Write.vi using port number 10,
and it will send a string to the parallel port. But, if you have not
yet modified your "labview.ini" file, you may receive an error -37.
I haven't use this method yet, so if it works, please email me.
