From Friday, April 19th (11:00 PM CDT) through Saturday, April 20th (2:00 PM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.
We appreciate your patience as we improve our online experience.
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.

Which OS do you use? Windows NT and Windows 2000 don't like direct port access. For these OSs you need a special file from the NI website ("hwaccess.xxx" oder "accesshw.xxx").
