It's an ugly scene. Even as Windows NT gains popularity across servers and desktops, the operating system lacks adequate support for scanners. The picture improved a bit with NT 4.0's arrival, but more work needs to be done.
NT 4.0 supports 32-bit TWAIN drivers, which work with SCSI-based scanners (available from companies like Epson, UMAX and Intergraph). However, NT still lacks support for bidirectional parallel ports used by popular scanners from Brother, Hewlett-Packard, Logitech and others. (Ironically, HP is standardizing its own corporate desktops on NT Workstation.)
NT's built-in parallel port driver supports only Enhanced Parallel Port (EPP) "nibble" mode, which isn't sufficient for scanners. Enhanced Capabilities Port (ECP) mode, used by Windows 95 Plug-and-Play scanners, won't be available for NT until late 1997 or early 1998.
