I don't think you can as it doesn't have an available USB port. I ran into the same problem recently and I ended up having to buy a new printer that ran off of a USB connection.

You can buy a Parallel Port to USB converter cable ~ $5 - $10. This allows bi-directional transfer of data from the printer via its parallel port to the new computer via one of its USB ports. Just make sure you get the right gender on the parallel side.
