If the bit number of the operating system does not match between the print server and the client computer, an additional driver may not be able to be installed normally in the print server.
To solve this problem, specify the setup information file (ntprint.inf) of the operating system with a different bit number when installing the additional driver on the print server.
The following describes how to install the additional driver by specifying a setup information file on a different computer from that of the print server.
The Additional Drivers page appears.
This displays a page to request a setup information file.
Specify the following file.
[z:\Windows\System32\DriverStore\FileRepository\ntprint.inf_xxx]
In the path above, "z" represents the assigned network drive. "_xxx" at the end of this path varies depending on the driver version.
The setup information file may be stored at a different location depending on your client computer. If folder [amd64] resides in the same hierarchy as that of [ntprint.inf], specify a setup information file for 64-bit operating system under that folder. To additionally install a 32-bit operating system driver, specify a setup information file under folder [i386] that is in the same hierarchy as that of [ntprint.inf].
Installation starts.
The additional installation of the 64-bit operating system driver is then completed.
