HP 722C Printer Sharing

Hi. I see a lot of us are having fun with Windows XP.
I am trying to share an HP 722c printer which is
connected to my desktop running WinXp.Home Edition. I
upgraded the desktop to WinXp. I have a laptop running
Win98. Before the upgrade, I was sharing the printer just
fine through my Linksys router. My laptop can see the
pc, folders and the printer but I cannot print over the
network from the laptop running Win98. The printer
prints fine directly from the pc with WinXp. I ran the
wizard on both computers. When I try to print a test
page from the laptop, nothing happens. If I try to
install a driver on the laptop (do I need one on the
laptop ?) the driver can't be found on the WinXp cd or my
Win98 cd. Please advise. Thanks.
