3–2 Printing with Your SuperScript 660SUPERSCRIPT660 PRINTMODESThe SuperScript lets you choose between two printmodes, GDI and PCL emulation.GDI mode, which prints what you see on yourscreen, is very fast and works well for most users.Printing in SuperScript PCL mode will be slowerthan GDI mode because GDI is the language ofWindows with direct access to Windows resources.PCL emulation gives you the ability to print from aDOS application running within Windows, and fromthe MS-DOS command line within Windows.You can select print mode from many Windowsapplications, or through the Control Panel’s Printerswindow. To print in GDI mode, select “NECSuperScript 660 GDI on NEC.GDI” as the currentprinter. To print in PCL emulation mode, select“NEC SuperScript 660 PCL on NEC.PCL”. If youhave installed the optional 200-sheet hopper, youshould see “NEC SuperScript 660 GDI 200 onNEC.GDI” and “NEC SuperScript 660 PCL 200 onNEC.PCL” instead.GDI mode takes advantage of Windows’ owninternal design to produce documents faster thanmost conventional printers can. Other printersrequire Windows to translate a document into aprinter language, such as PCL on LaserJet printers.GDI mode reduces overhead by eliminating thistranslation step before starting to print. This resultsin faster printing—as much as three times faster forsome files. SuperScript GDI mode includes someadditional features such as manual duplex printing,density control, scaling, and forms overlay.GDI MODE
