XP/98 Printer Sharing

Hello All,
I have a Win XP computer with 2 Win 98SE computers
attached to it via a Linksys router. All computers can
access the internet and each other's shared resources just
fine, BUT I cannot get the 2 win 98 machines to print to
the network printer on the win xp box. The printer shows
up when 'browsing' for a new network printer and the
software installs from the disk when prompted. However,
nothing prints!
One interesting thing is that when browsing for the
printer, all that shows up is 'Printer4' rather than the
actual printer name as entered on the win xp box, Epson
Color Stylus 740. Could this have anything to do with an
XP-specific print driver on the xp box vs the 98 drivers
on the other 2?
Any help for this frustrating problem would be GREATLY
appreciated!
Cheers,
Phil
