I have a Dell Optiplex GX270 I am trying to connect to a HP Office Jet 6310 All-In-One Printer via a Belkin A,B,C,D Data Switch. I am coming off of the GX270 from the LPT1 port to the switch's LPT1 B side and from the I/O (LPT1) port on the switch to the printer with a LPT1 to USB cable to a USB A to B transgender adaptor. I cannot seem to get the GX270's LPT1 port to recognize the USB device to make it functional. Any suggestions will be greatly appreciated.
