Printer drops offline in wireless network

I have 2 networked computers, one XP and one Vista, sharing a printer through
a wireless router. The printer is always online with the XP, but regularly
drops offline with the Vista. I've found no way to get the printer back
online except to reinstall it. How can I keep the printer from dropping out,
or at least get the printer back online without reinstalling?
