using ubuntu 10.0.4 as a print server for windows servers and clients..

I have a fresh test install of ubuntu 10.0.4. I am very new to linux but have a good grasp of a lot of the features and a good birds eye view of what I can accomplish with it. Here's what I'm trying to do and what I've done so far...

I have a ubuntu fresh 64 bit install of ubuntu 10.0.4, we'll call PS01.I have this connected to a network of windows PCs varying between windows 2k,2k3,XP,Vista,7. I also have a few 64 bit clients (my machine) mixed in with the 32 bit clients. I wanto to make the ubuntu client a print server so that my windows clients can use it as a print server. I have installed all the updates using the update manager(using the ubuntu default repositories....)

I have added CUPS and SAMBA from the synpatics package installer I'm not really sure if CUPs is doing anything but I got SAMBA to work. I have a printer (HP LJ M1522NFP) setup and installed on PS01. I can print locally and I was able to connect my windows machine to it by going to the webshare \\ps01\, right clicking on my printer and hitting connect. My problem is that I am prompted to provide a location for drivers. I imagine that there is some way that ubuntu uses a repository for drivers where I can provide my different drivers for the OSes that are connecting to my printer server so they won't have to go searching for the drivers? Also when I installed the printer on my XP client, the printer prints fine but the status of the printer says access denied. unable to connect always? anyway to change that?
