Since I have now bought the item for the second time I thought must evaluate him once.
Shortly to my application:
Searched by me a real Retrofit LPT port for controlling my CNC machine via laptop.
I have before I bought the Delock 66220 tested 5 different LPT ports.
USB> LPT 1x and 1x Noname brand
PCMCIA 1x and 1x Delock Noname which model I know exactly garnicht more.
1x DIY the wiring diagram on the Internet (eigentlicha uch only a USB> LPT.
Problem with all you simulate a LPT (printer port) Say it is not a LPT port appears in Device Manager and therefore they are not to be used for any CNC software.
Advantages of Delock 66220 are:
Super Reliable
There is no need for drivers
It's a real LPT port
He is ready for very small and inenrhalb 2 seconds
I buy him now only the second time since I have him even damaged due to a short-circuit.
I can only recommend this device, the price worth it definitely.
