Using PC as a emulated hard drive or floppy disk

[hgnhnnyt]

I have another question is it possible to connect my pc to my hp-150 with a usb to db25 connector through the parallel port on the hp-150 and if so what emulator would i need to use. And what specific cable do i need. Like null modem or straight i think it would just be a straight rs232 db25. I'm trying to do something like this https://www.hp9845.net/9845/projects/hpdrive/ but with the parallel card on the hp-150 and not gpib.
