Install 64 bit print driver on SBS 2003 32 bit server

Install the driver on the 64 bit computer.
Open the printer properties from that computer and click on the add aditional drivers.
Select the check box for x64.
Let the server take the drivers from the PC.
This will install them.

ps... the driver versions... x86 and x64 must match... Just remember... do it from the x64 computer, not the server. Good Luck.

Usually I have to do the reverse...getting 32 bit drivers onto a 64 bit printer server.  Log into the 64 bit computer as an administrator who admin access over the 2003 box.  Run printmanagement.msc and under Print Servers, add your server in.  Install the drivers through this and see if you get the same errors.

Well, guys, this is what I did:

1.  On 64-bit client computer ran printmanagement.msc. I selected "Add Print Server".
2.  A list was presented to me, and I selected SERVER1 and hit "apply".
3.  I was presented with 2 print servers:  JEREMY-PC and SERVER1.
4.  SERVER1 print server was blank.
5.  Under SERVER1 I highlighted "Printers", hit the right mouse button and selected "Add Printer".
6.  Through "network printer search", 2 printers popped up:  iR3045 and HP4200.
7.  I selected HP4200 and clicked NEXT.
8.  A message appeared "no printer driver found". There was also the option to "Add from Disk".

Here is where I stopped. I don't understand why the HP4200 printer driver was not found in the "drivestore\filerepository". (As a test, I was able to successfully install an HP4200 printer as a "local printer" without problem or error.)

At this point, I can try to point the "Add from Disk" to the HP4200 Universal 64-bit drivers I downloaded from HP. Any suggestions or where am I going astray? Does the above sound kosher or are there additional problems?

You can install drivers directly at the server console. However it may fail when the driver model doesn't match the server OS (i.e. Loading a 32-bit driver on a 64-bit server and vice-versa). I too also had these issues hen I first started deploying 64-bit OSes. But here's the way I've found that has always worked for me.

1. Logon an domain administrator on the Windows 7 workstation.
2. Click the Windows Logo->Search. Enter "\\<servername>". So if you server is server1 then enter "\\server1" (without the quotes) and press enter.
3. A windows showing all the file shares on the server is displayed. At the top click on view remote printers.
4. A list of printer shares on the server is shown. Right click (not on an icon) and choose Server Properties.
5. A new window appears. Notice it says "Print Server on <server name> Properties. Click on the Drivers tab. Click Add button and complete the add driver wizard. The 64-bit driver is now installed on the server. It will now be available for download to any 64-bit system that's setup to use a printer requiring it.
6. You can click the add button again to add any additional drivers needed.

Note: It seems a bit strange to have to add the driver from a workstation but this avoids the issue of the installation asking for 32-bit or 64-bit specific files.

None of the solutions suggested worked. I had to call HP and Dell for a solution.
