Wrong!

The parallel port starts up in an undefined state in windows, the USB starts up in a power down state and is kept that way by the shoestring product.

So start a scope with parallel port attacher guider and things may go astray as I found. You can get by by creating a text file with a binary editor and writing binary null (00) to it then binary copying (copy /b ) this file as a start up service under windows to the LPT1 port

create a file called null.txt and a null.bat file with the follwoing DOS command in it, then add it as a scheduled task under Control Panel

copy /b c:\null.txt LPT1

The printer port remembers the last data written to it and keeps re-broadcasting, so writing binary zero fixes the issue - but what a hassle!

So I'd recommend the parallel port - and think this warning should be on the parallel port version!
