1.6 Output Devices
==================

GNU 'troff''s output is in a device-independent page description
language, which is then read by an "output driver" that translates this
language into a file format or byte stream that a piece of (possibly
emulated) hardware understands.  'groff' features output drivers for
PostScript devices, terminal emulators (and other simple typewriter-like
machines), X11 (for previewing), TeX DVI, HP LaserJet 4/PCL5 and Canon
LBP printers (which use CaPSL), HTML, XHTML, and PDF.
