A
printer that has built-in
support for
Windows Graphical Device Interface (GDI). GDI is used by most Windows
applications to display images on a
monitor, so when printing from a Windows application to a GDI printer, there is no need to
convert the
output to another
format such as
PostScript or
PCL.
GDI printers are sometimes called host-based printers because they rely on the host computer to rasterize pages.
