Background - Kernel Mode Drivers vs. User Mode
(excerpt
taken from Microsoft Windows Printing Interoperability Abstract)
In Windows NT 4.0 all printer drivers run in kernel mode. The Windows printing
environment refers to these drivers as Version 2 drivers. For Windows 2000 and later
Microsoft moved to user mode drivers (called Version 3 drivers) for system reliability and
robustness. Windows 2000 and later environments support user mode drivers natively,
and kernel mode drivers solely for backward compatibility. A driver error that occurs in
kernel mode is able to crash the entire server, while the effect of an error in user mode is
restricted to the driver process, generally the spooler. Restarting the spooler is much
faster than rebooting the entire system, and allows other services on the server to
continue while the spooler is down.
