Apple Color LaserWriter 12/600 PS - Manual (Page 115)

Setting printer driver options
You can change the PostScript Printer Driver default options. For example,
you can change the preset paper orientation to Portrait or Landscape.
You set printer options in the printer driver Setup dialog box, which you can
open in three ways, as explained in the sections that follow:
m from the Control Panel
m from your application
m from the Print Manager
Note: When changing options to print a specific document, it’s preferable to
change the options from within the application. Settings you change from
within an application will affect that document only and not all documents
printed afterward. Settings you change in an application’s Print dialog box
override print options you set in the Setup dialog box.
Opening the printer Setup dialog box from the Control Panel
1 From the Program Manager, double-click the Control Panel icon to display the
Control Panel.
2 Double-click the Printers icon to display the Printers dialog box.
3 Select the printer you want to set up from the Installed Printers list.
4 Choose Setup to display the Setup dialog box for the printer.
You can also use the Printers dialog box to select a default printer, to switch
the Print Manager on and off, and to connect your printer to a different port.
