Synchronize HP Printer/Fax Clock

After the stellar success of my cellular phone clock synchronization script, I had an idea: why not synchronize the printer clock too?

We have an HP OfficeJet 5510 printer/fax/scanner/copier combo, which is hooked directly to my laptop over USB. Its front panel clock tends to drift quite a bit, and I usually forget to switch it from/to Daylight savings time.

It took about two minutes to find hp-timedate, and here's the corresponding cron job specification:
 10 4    *   *   *   /usr/bin/hp-timedate
Now, how do I interface my laptop with the microwave oven?
