Hewlett Packard Laser Jet 4 printer – serial cable type MFg 1994

I need to connect my HP Laser jet 4 plus to my laptop computer.

I cannot find my driver hardware for the printer and I do not know what type of connector I need in order to connect a serial cable from the printer to a usb input to my computer.

The printer I am using now is just way to slow to use.

Thanks, I really need to get this up and running immediately. I use it for tax reports for clients.
