Driver for this is included with XP. Since you don't have the disk, check
your machine for an I386 folder - this includes the installation files that
should include the drivers. If you don't have that, can you borrow a disk?
(For that matter, do you have a COA showing that your copy of XP is legit?)
If you still want the driver, a little googling would have eventually
brought you here:

FWIW, you'll get better throughput to the printer by using a USB to Parallel
converter cable rather than just hooking it up to the parallel port. XP, by
design, poorly supports parallel port operation.
