Can't print from XP client to either ot 2 Win98 hosts

I have a small office network networked by a Linksys DSL
Firewall VPN Router. I can access Hard Drives, Floppies,
and CD's from any computer to any other.

I can print from Computer A running Windows 98 to
Computer B running Windows 98 and its Samsung Laser
Printer.

I can print from Computer B to Computer A and its HPIII
laser printer.

However, I can not Print from Computer C running Windows
XP Home Edition to either printer attached to Computer A
or B.

The XP Printer drivers for the other 2 printers are
loaded on Computer C. The Printer Wizard on Computer C
and browse the network and find the other 2 printers.

When you try to print from Computer C to either of the
other printers it gives a message "unable to create a
print job"

Computer C has a HP LJ3100 attached directly to it

All Computer's can print to the printer attached to
itself.

Any suggestions?
