Printing through iMac from PC

I have a network consisting of iMac (OS X 3.3.3), PC (WIN98se),
EpsonStylus PHOTO 925, D-Link 604 router, and Motorola Surfboard cable
modem. The modem is connected to the WAN on the D-Link. The iMac and
PC are connected to LAN ports on the D-Link. The printer is connected
to the iMac via USB. I've identified share properties on both the iMac
and PC. Both the iMac and PC connect just fine to the internet through
the modem; the iMac prints to the printer; I am able to view and send
files back and between the iMac to the PC. I've installed the
appropriate drivers for the printer in both the iMac and PC. I've
enabled file and print sharing on both the iMac and PC.

However I am unable to print to the printer from the PC. Please respond
stating or referencing the appropriate setup for the PC to permit using
the printer from the PC.
