For print servers, running a 64-bit version of Windows, and supporting client computers running 32-bit versions of Windows, you must add x86-based drivers for each printer as well as the x64 bit.
You can add printer drivers that are up to 2GB in size. You will not be able to back up printer drivers that are larger than 2GB.
To add client printer drivers to the print server, first make sure to have the drivers downloaded and placed on your machine. The drivers need to be tested before putting on the production server.

If the print server does not already have the appropriate printer drivers in its driver store, Windows prompts you for the location of the driver files. Download and extract the appropriate driver files, and then in the dialog box that appears, specify the path to the .inf file of the driver.
You might not be able to extract some printer drivers without installing them. If this is the case, log on to a client computer that uses the same processor architecture as the printer drivers that you want to add to the print server, and install those printer drivers. Then use Print Management from the client computer to connect to the print server, and add the additional drivers from the Additional Drivers dialog box. Windows automatically uploads the drivers from the client computer to the print server.
To update or change the printer drivers for a printer, use the following procedure. Client computers automatically download and install the updated printer drivers the next time they attempt to print to the printer.
When installing printer drivers that are provided by the device manufacturer, follow the instructions provided with the printer driver instead of using this procedure.
