Is network printing possible without an LPT port

I built a workstation for our CEO using a server dual xeon motherboard with XP installed as sort of an overkill hotrod.  Now that it is together, I realized that the motherboard does not have an LPT port.  I don’t mean it does not have an LPT printer connection, it does not have an LPT port, not in the bios or listed in system/hardware/ports and an LPT port cannot be added manually as additional hardware.  The port specs in system hardware show com1 com2 and nothing else.  

Checking on the SuperMicro web site I learned that the other SuperMicro motherboards in this series all have an LPT port listed in the IO specs.  This X7DVL-L motherboard does not list an LPT port in the IO specs.  

The problem:
This machine finds the network printers, but it won’t print.  It will print to a printer connected to a usb port, but not to the network printers.  

We have 14 workstation on this domain, one of them is a dual xeon server motherboard similar to the workstation in question and it prints as expected. (it has an LPT port) This domain has a Proliant DL380 running Server 2003 64-bit.  32-bit printer drivers are available for the workstations.

The only difference in the machine that fails to print that I can see is the non-existant LPT port.  I asked in a previous question if an LPT port was necessary for network printing and I was told it was not necessary.  I am second guessing since I cannot find anything else different about this machine.  Again, I am not talking about a printer connection, rather the port.

What am I missing?  thanks
