    Of course, he'd have to route the LPT output to the serial output, but, with LSDOS, that's pretty simple.
    I doubt that it would work.

    As Krebizfan points out you're going the wrong way. The 'master' driving the transfer has to be at the USB end, assumed to be a computer; the printer would not know how to set up the communication.

    The USB connector on the printer is also different, and finally most if not all modern printers are dumb and rely on the computer to assemble the necessary pixel patterns to print characters etc.

    You'd need something like a Pi or even an old DOS box in between.

    Yes, you're right, Mike, I looked at the USB printers I have and they all use the (sorta) D shaped input to the printer as opposed to the flat one.

    I figured the Tandy to PC to printer route when he first asked but thought this looked easier.

    Back to the drawing board.....

    Is the newer PC a laptop? If it's a desktop with PCI slots, why not use a PCI serial port card?

    Not a laptop, but a Mac Mini so essentially treated the same as a laptop.
