In order for a Windows NT print server to support the downloading of driver files by multiple client architectures, you must create several subdirectories within the [print$] service (i.e., the UNIX directory named by the path parameter). These correspond to each of the supported client architectures. Samba follows this model as well. Just like the name of the [print$] share itself, the subdirectories must be exactly the names listed below (you may leave out the subdirectories of architectures you do not need to support).

Therefore, create a directory tree below the [print$] share for each architecture you wish to support like this:

[print$]--+
          |--W32X86           # serves drivers to Windows NT x86
          |--WIN40            # serves drivers to Windows 95/98
          |--W32ALPHA         # serves drivers to Windows NT Alpha_AXP
          |--W32MIPS          # serves drivers to Windows NT R4000
          |--W32PPC           # serves drivers to Windows NT PowerPC
