I strongly suggest someone with a parallel printer use one of these kinds of USB adapters instead of trying to share a parallel port between a mill and a printer. http://www.newegg.com/Product/Product.aspx?Item=N82E16812150015 Or, get another parallel port: http://www.newegg.com/Product/Product.aspx?Item=N82E16815104211 I think these schemes for sharing the port are bad advice (which Jeff also said above). For under $10 you can have your pick of good solutions instead (I have not tried these particular products, but I have experience with similar.) ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
