Unable to print to windows printer

[Anonymous]

I am so baffled by this.
I have an HP DeskJet932C hooked up to a WindowsXP computer on my network.  In Samba I can mount shares just fine.  I can even SEE the shared printer when I browse the network in LinNeighborhood.  But I cannot print to it.  I've tried using smb://guest:@officepc/hpdj and many other variations but nothing works (yes the guest account is enabled).  I then decided to try LPD.  I have the Print Services for Unix installed on my XP machine.  I added the printer in the Cups in the form lpd://192.168.0.2/hpdj but then I get the following error.

"Network host '192.168.0.2' is busy, down, or unreachable; will retry in 30 seconds..."

I am able to ping 192.168.0.2 so I know that it's the right IP address for that computer.

Does anybody have any other ideas for things I could try?

Thanks
