RE: Write to Parallel port

[Paul]

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").
