Error parallel port VISA write

I've been trying to run the parallel test vi as refered to at:

http://zone.ni.com/devzone/conceptd.nsf/webmain/72C6FC6CE4AD4D1386256B1800794596?opendocument

I get the following error:

###

Error -1073807339 occurred at VISA Write in Parallel Exp.vi

Possible reason(s):

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

###

Is it possible that the pin11(Busy) and pin12(Paper Error) are interfering with the write -- hence the above timeout error? The document suggests to tie these pins to ground (at the moment they aren't).

Appreciate the help.

System:
win2000pro
labview7.1

Thanks!

Bill

That is the first thing I would do. Pull the Busy and Paper Out Pins on the parallel Port Low.

Second check the enumeration of the parallel Port. The same article tells you how to do it.

I beleive adding a line ...

serialDevices="COM1; COM2; COM3; COM4; LPT1;"

in Labview.ini file will enumerate it at 4
Good Luck!

The pin11 and pin12 pulldown did fix the problem. Thanks!
