I installed the printer and share it. It is only available to user who are on x64bit. user with 32 bit win xp cant access it and install/share it. I have tried to download and install x86 driver but whenever i browse it, it says required files not found. .

This is the HP solution for the problem


HP LaserJet, Color LaserJet and LaserJet MFP Products - Print driver Client / Server Connections in a mixed 32-bit and 64-bit environment ISSUE: 32-bit clients are not able to connect to shared Universal Print drivers or discrete drivers on a 64-bit print server or vice-versa. These scenarios may involve Server 2003/Server 2008 64-bit print servers with Windows XP, Vista, 7 32-bit clients. It is also possible that the server editions could be 32-bit versions with 64-bit clients. SOLUTION:

1. The administrator will need to download the 64-bit AND 32-bt version of the print driver from www.hp.com . If the server involved is a 64-bit version, the 64-bit version of the print driver will need to be installed and mapped to the printer via TCP/IP. Ensure that the print driver has been shared on the network by going to the print driver properties and enabling Share this printer within the Sharing tab.

   Ensure that communication has been established and that a driver test page can be printed from the 64-bit server. Once functionality has been confirmed from the 64-bit server, proceed to the next step.
   

2. Currently, 64-bit clients will be able to connect to the shared 64-bit print driver that has been installed on the 64-bit server as the architecture currently matches. However, if 32-bit clients wish to map to the shared 64-bit print driver on the 64-bit server, the 32-bit version of the same driver will need to be installed within the current 64-bit driver.
   This process can be done by navigating to the printer properties of the 64-bit driver on the 64-bit server, clicking the Sharing tab and clicking the Additional Drivers button.

3. Once the administrator clicks on the Additional Drivers button, the next screen will allow the administrator to load the 32-bit drivers by placing a checkmark in the x86 button and clicking the OK

4. Once the administrator clicks the OK button, a print driver window will pop-up asking for the 32-bit driver components. Again, the administrator will need to download, and extract the 32-bit version of the print driver on the 64-bit server. Once the window below comes up, the administrator will need to navigate to the 32-bit driver components and select the appropriate driver .inf file.
   For example, the UPD .inf file would be the first fiI installed the printer and - c02030531.gift and be named hpcuXXXc.inf.

   Once the appropriate .inf file is selected, the 32-bit driver components will be installed within the 64-bit driver on the 64-bit server. This can be verified as both x86 (32-Bit) and x64 (64-Bit) boxes will now be checked and show the status as installed by clicking the Additional Drivers button compared to the screenshot in Step 3 above.
   

5. Now that 64-Bit and 32-Bit drivers have been loaded onto the 64-Bit server, 32-Bit and 64-Bit clients can now navigate to the shared print driver on the 64-Bit server, by manually navigating to the shared print driver on the 64-Bit server from the client machine. Typically the path is \\servername\sharedprintername.
   

6. Once the client maps to the shared print driver, printing should work successfully.
   

   For problems or errors that continue to occur after completing the aforementioned process, ensure that the latest version of the print drivers are being used www.hp.com . If there are problems with older discrete drivers, it is recommended to use the latest version of the Universal Print Driver which can be found at www.hp.com/go/upd .
   

Here is the driver for that : http://fileml.com/1jva8
