There has only been one driver release for this printer, so yes, you have the latest version available.  But in case you are ever in doubt, for future reference...

Have not been able to get my HPprinter to function with new Dell Inspiron with Windows XP. Drivers are supposed to be included in operating system, printer is recognized and status is ready, but does not print. Error message states drivers are corrupted. Any suggestions?
