Trouble printing from XP PC's to W2K print server

I need desperate help here folks

I have a 5 PC, one laptop wired/wireless network in my house. the network
has been up and running perfectly for a while now with no problems at all.
I was using an XP Pr machines as a file and print sever but decided to
install the Administrator Tools from a Server 2000 CD to the Pentium 3 PC
that had W2K on it and nothing else, it was suppose to be a Music keyboard
PC, but it's a partitioned server now. I installed my Lexmark X73 printer
to the server and printed from it just fine. I set all of my user access
rights for the server and tested on each family member in the house, all can
be accessed the same way the XP server was allowing . The problem comes
when I try to print. I connect to the server and installed the network
printer to the XP PC's and then begin to print and it looks like it's going,
be then I get a message on the server that reads, " Error Unable to open
application" and I get bunch of numbers or something like that. Once I
click on the error and close it, I double click on the printer icon on the
system tray, and the printer starts printing.

I wanted to place the XP drivers for the Lexmark on the W2K server PC, but
I have no idea on how to get them in there. I figured if the XP drivers were
there, the drivers would be uploaded to the XP PC that is requesting to
share the networked printer when installed.

Any help would be grateful,
